The British Museum is a public museum dedicated to human history, art and culture located in the Bloomsbury area of London. Its permanent collection of eight million works is the largest in the world. It documents the story of human culture from its beginnings to the present. Established in 1753, the British Museum was the world's first public national museum. In 2025, the museum received 6,440,120 visitors and was the second most visited attraction in the United Kingdom.

At its beginning, the museum was largely based on the collections of the Anglo-Irish physician and scientist Sir Hans Sloane. It opened to the public in 1759, in Montagu House, on the site of the current building. The museum's expansion over the following 250 years was largely a result of British colonisation and resulted in the creation of several branch institutions, or independent spin-offs, the first being the Natural History Museum in 1881. Some of its best-known acquisitions, such as the Greek Elgin Marbles and the Egyptian Rosetta Stone, are subject to long-term disputes and repatriation claims.

In 1973, the British Library Act 1972 detached the library department from the British Museum, but it continued to host the now separated British Library in the same Reading Room and building as the museum until 1997. The museum is a non-departmental public body sponsored by the Department for Culture, Media and Sport. Like all UK national museums, it charges no admission fee except for loan exhibitions.

History

Sir Hans Sloane

Although today principally a museum of cultural art objects and antiquities, the British Museum was founded as a "universal museum". Its foundations lie in the will of the Anglo-Irish physician and naturalist Sir Hans Sloane (1660–1753), a London-based doctor and scientist from Ulster. During the course of his lifetime, and particularly after he married the widow of a wealthy Jamaican planter, Sloane gathered a large collection of curiosities, and not wishing to see his collection broken up after death he bequeathed it to King George II, for the nation, for a sum of £20,000 (equivalent to £3,834,052 in 2025) to be paid to his heirs by Parliament—intentionally far less than the estimated value of the artefacts, contemporarily estimated at £50,000 (equivalent to £9,585,130 in 2025) or more according to some sources, and up to £80,000 (equivalent to £15,336,208 in 2025) or more by others.

At that time, Sloane's collection consisted of around 71,000 objects of all kinds including some 40,000 printed books, 7,000 manuscripts, extensive natural history specimens including 337 volumes of dried plants, prints and drawings including those by Albrecht Dürer and antiquities from Sudan, Egypt, Greece, Rome, the Ancient Near and Far East and the Americas.

Foundation (1753)

On 7 June 1753, King George II gave his royal assent to the act of Parliament which established the British Museum. The British Museum Act 1753 also added two other libraries to the Sloane collection, namely the Cottonian Library, assembled by Sir Robert Cotton, dating back to Elizabethan times, and the Harleian Library, the collection of Robert Harley, 1st Earl of Oxford and Mortimer. They were joined in 1757 by the "Old Royal Library", now the Royal manuscripts, assembled by various British monarchs. Together these four "foundation collections" included many of the most treasured books now in the British Library including the Lindisfarne Gospels and the sole surviving manuscript of Beowulf.

The British Museum was the first of a new kind of museum – national, belonging to neither church nor king, freely open to the public and aiming to collect everything. Sloane's collection, while including a vast miscellany of objects, tended to reflect his scientific interests. The addition of the Cotton and Harley manuscripts introduced a literary and antiquarian element, and meant that the British Museum now became both National Museum and library.

Cabinet of curiosities (1753–1778)

The body of trustees decided on a converted 17th-century mansion, Montagu House, as a location for the museum, which it bought from the Montagu family for £20,000. The trustees rejected Buckingham House, which was later converted into the present day Buckingham Palace, on the grounds of cost and the unsuitability of its location.

With the acquisition of Montagu House, the first exhibition galleries and reading room for scholars opened on 15 January 1759. At this time, the largest parts of collection were the library, which took up the majority of the rooms on the ground floor and the natural history objects, which took up an entire wing on the first floor. In 1763, the trustees of the British Museum, under the influence of Peter Collinson and William Watson, employed the former student of Carl Linnaeus, Daniel Solander, to reclassify the natural history collection according to the Linnaean system, thereby making the museum a public centre of learning accessible to the full range of European natural historians. In 1823, George IV gave the King's Library assembled by George III, and Parliament gave the right to a copy of every book published in the country, thereby ensuring that the museum's library would expand indefinitely. During the few years after its foundation the British Museum received several further gifts, including the Thomason Collection of Civil War Tracts and David Garrick's library of 1,000 printed plays. The predominance of natural history, books and manuscripts began to lessen when in 1772 the museum acquired for £8,410 its first significant antiquities in Sir William Hamilton's "first" collection of Greek vases.

Indolence and energy (1778–1800)

From 1778, a display of objects from the South Seas brought back from the round-the-world voyages of Captain James Cook and the travels of other explorers fascinated visitors with a glimpse of previously unknown lands. The bequest of a collection of books, engraved gems, coins, prints and drawings by Clayton Mordaunt Cracherode in 1800 did much to raise the museum's reputation; but Montagu House became increasingly crowded and decrepit and it was apparent that it would be unable to cope with further expansion.

The museum's first notable addition towards its collection of antiquities, since its foundation, was by Sir William Hamilton (1730–1803), British Ambassador to Naples, who sold his collection of Greek and Roman artefacts to the museum in 1784 together with a number of other antiquities and natural history specimens. A list of donations to the museum, dated 31 January 1784, refers to the Hamilton bequest of a "Colossal Foot of an Apollo in Marble". It was one of two antiquities of Hamilton's collection drawn for him by Francesco Progenie, a pupil of Pietro Fabris, who also contributed a number of drawings of Mount Vesuvius sent by Hamilton to the Royal Society in London.

Growth and change (1800–1825)

In the early 19th century the foundations for the extensive collection of sculpture began to be laid and Greek, Roman and Egyptian artefacts dominated the antiquities displays. After the defeat of the French campaign in the Battle of the Nile, in 1801, the British Museum acquired more Egyptian sculptures and in 1802 King George III presented the Rosetta Stone – key to the deciphering of hieroglyphs. Gifts and purchases from Henry Salt, British consul general in Egypt, beginning with the Colossal bust of Ramesses II in 1818, laid the foundations of the collection of Egyptian Monumental Sculpture. Many Greek sculptures followed, notably the first purpose-built exhibition space, the Charles Towneley collection, much of it Roman sculpture, in 1805. In 1806, Thomas Bruce, 7th Earl of Elgin, ambassador to the Ottoman Empire from 1799 to 1803 removed the large collection of marble sculptures from the Parthenon, on the Acropolis of Athens and transferred them to the UK. In 1816 these masterpieces of western art were acquired by the British Museum by the British Museum Act 1816 (56 Geo. 3. c. 99) and deposited in the museum thereafter. The collections were supplemented by the Bassae frieze from Phigaleia, Greece in 1815. The Ancient Near Eastern collection also had its beginnings in 1825 with the purchase of Assyrian and Babylonian antiquities from Mary Mackintosh Rich, the widow of Assyriologist Claudius James Rich.

In 1802 a buildings committee was set up to plan for expansion of the museum, and further highlighted by the donation in 1822 of the King's Library, personal library of King George III, comprising 65,000 volumes, 19,000 pamphlets, maps, charts and topographical drawings. The neoclassical architect, Sir Robert Smirke, was asked to draw up plans for an eastern extension to the museum "... for the reception of the Royal Library, and a Picture Gallery over it ..." and put forward plans for today's quadrangular building, much of which can be seen today. The dilapidated Old Montagu House was demolished and work on the King's Library Gallery began in 1823. The extension, the East Wing, was completed by 1831. However, following the founding of the National Gallery, London in 1824, the proposed Picture Gallery was no longer needed, and the space on the upper floor was given over to the Natural history collections.

The first Synopsis of the British Museum was published in 1808. This described the contents of the museum, and the display of objects room by room, and updated editions were published every few years.

Largest building site in Europe (1825–1850)

As Sir Robert Smirke's grand neo-classical building gradually arose, the museum became a construction site. The King's Library, on the ground floor of the East Wing, was handed over in 1827, and was described as one of the finest rooms in London. Although it was not fully open to the general public until 1857, special openings were arranged during The Great Exhibition of 1851.

In 1840, the museum became involved in its first overseas excavations, Charles Fellows's expedition to Xanthos, in Asia Minor, whence came remains of the tombs of the rulers of ancient Lycia, among them the Nereid and Payava monuments. In 1857, Charles Newton was to discover the 4th-century BC Mausoleum at Halicarnassus, one of the Seven Wonders of the Ancient World. In the 1840s and 1850s the museum supported excavations in Assyria by A.H. Layard and others at sites such as Nimrud and Nineveh. Of particular interest to curators was the eventual discovery of Ashurbanipal's great library of cuneiform tablets, which helped to make the museum a focus for Assyrian studies.

Sir Thomas Grenville (1755–1846), a trustee of the British Museum from 1830, assembled a library of 20,240 volumes, which he left to the museum in his will. The books arrived in January 1847 in twenty-one horse-drawn vans. The only vacant space for this large library was a room originally intended for manuscripts, between the Front Entrance Hall and the Manuscript Saloon. The books remained here until the British Library moved to St Pancras in 1998.

Collecting from the wider world (1850–1875)

The opening of the forecourt in 1852 marked the completion of Robert Smirke's 1823 plan, but already adjustments were having to be made to cope with the unforeseen growth of the collections. Infill galleries were constructed for Assyrian sculptures and Sydney Smirke's Round Reading Room, with space for a million books, opened in 1857. Because of continued pressure on space the decision was taken to move natural history to a new building in South Kensington, which would later become the British Museum of Natural History.

Roughly contemporary with the construction of the new building was the career of a man sometimes called the "second founder" of the British Museum, the Italian librarian Anthony Panizzi. Under his supervision, the British Museum Library (now part of the British Library) quintupled in size and became a well-organised institution worthy of being called a national library, the largest library in the world after the National Library of Paris. The quadrangle at the centre of Smirke's design proved to be a waste of valuable space and was filled at Panizzi's request by a circular Reading Room of cast iron, designed by Smirke's brother, Sydney Smirke.

Until the mid-19th century, the museum's collections were relatively circumscribed but, in 1851, with the appointment to the staff of Augustus Wollaston Franks to curate the collections, the museum began for the first time to collect British and European medieval antiquities, prehistory, branching out into Asia and diversifying its holdings of ethnography. A real coup for the museum was the purchase in 1867, over French objections, of the Duke of Blacas's wide-ranging and valuable collection of antiquities. Overseas excavations continued and John Turtle Wood discovered the remains of the 4th century BC Temple of Artemis at Ephesus, another Wonder of the Ancient World.

Scholarship and legacies (1875–1900)

The natural history collections were an integral part of the British Museum until their removal to the new British Museum of Natural History in 1887, nowadays the Natural History Museum in South Kensington. With the departure and the completion of the new White Wing (fronting Montague Street) in 1884, more space was available for antiquities and ethnography and the library could further expand. This was a time of innovation as electric lighting was introduced in the Reading Room and exhibition galleries.

The William Burges collection of armoury was bequeathed to the museum in 1881. In 1882, the museum was involved in the establishment of the independent Egypt Exploration Fund (now Society) the first British body to carry out research in Egypt. A bequest from Miss Emma Turner in 1892 financed excavations in Cyprus. In 1897 the death of the great collector and curator, A. W. Franks, was followed by an immense bequest of 3,300 finger rings, 153 drinking vessels, 512 pieces of continental porcelain, 1,500 netsuke, 850 inro, over 30,000 bookplates and miscellaneous items of jewellery and plate, among them the Oxus Treasure.

In 1898 Baron Ferdinand de Rothschild bequeathed the Waddesdon Bequest, the glittering contents from his New Smoking Room at Waddesdon Manor. This consisted of almost 300 pieces of objets d'art et de vertu which included exquisite examples of jewellery, plate, enamel, carvings, glass and maiolica, among them the Holy Thorn Reliquary, probably created in the 1390s in Paris for John, Duke of Berry. The collection was in the tradition of a Schatzkammer such as those formed by the Renaissance princes of Europe. Baron Ferdinand's will was most specific, and failure to observe the terms would make it void, the collection should be

placed in a special room to be called the Waddesdon Bequest Room separate and apart from the other contents of the Museum and thenceforth for ever thereafter, keep the same in such room or in some other room to be substituted for it. These terms are still observed, and the collection occupies room 2a.

New century, new building (1900–1925)

By the last years of the 19th century, The British Museum's collections had increased to the extent that its building was no longer large enough. In 1895 the trustees purchased the 69 houses surrounding the museum with the intention of demolishing them and building around the west, north and east sides of the museum. The first stage was the construction of the northern wing beginning 1906.

All the while, the collections kept growing. Emil Torday collected in Central Africa, Aurel Stein in Central Asia, D. G. Hogarth, Leonard Woolley and T. E. Lawrence excavated at Carchemish. Around this time, the American collector and philanthropist J. Pierpont Morgan donated a substantial number of objects to the museum, including William Greenwell's collection of prehistoric artefacts from across Europe which he had purchased for £10,000 in 1908. Morgan had also acquired a major part of Sir John Evans's coin collection, which was later sold to the museum by his son J. P. Morgan Jr. in 1915. In 1918, because of the threat of wartime bombing, some objects were evacuated via the London Post Office Railway to Holborn, the National Library of Wales (Aberystwyth) and a country house near Malvern. On the return of antiquities from wartime storage in 1919 some objects were found to have deteriorated. A conservation laboratory was set up in May 1920 and became a permanent department in 1931. It is today the oldest in continuous existence. In 1923, the British Museum welcomed over one million visitors.

Disruption and reconstruction (1925–1950)

New mezzanine floors were constructed and book stacks rebuilt in an attempt to cope with the flood of books. In 1931, the art dealer Sir Joseph Duveen offered funds to build a gallery for the Parthenon sculptures. Designed by the American architect John Russell Pope, it was completed in 1938. The appearance of the exhibition galleries began to change as dark Victorian reds gave way to modern pastel shades.

Following the retirement of George Francis Hill as Director and Principal Librarian in 1936, he was succeeded by John Forsdyke.

As tensions with Nazi Germany developed and it appeared that war may be imminent Forsdyke came to the view that with the likelihood of far worse air-raids than that experienced in World War I that the museum had to make preparations to remove its most valuable items to secure locations. Following the Munich crisis Forsdyke ordered 3,300 No-Nail Boxes and stored them in the basement of the Duveen Gallery. At the same time he began identifying and securing suitable locations. As a result, the museum was able to quickly commence relocating selected items on 24 August 1939, (a mere day after the Home Secretary advised them to do so), to secure basements, country houses, Aldwych tube station and the National Library of Wales. Many items were relocated in early 1942 from their initial dispersal locations to a newly developed facility at Westwood Quarry in Wiltshire.

The evacuation was timely, for in 1940 the Duveen Gallery was severely damaged by bombing. Meanwhile, prior to the war, the Nazis had sent a researcher to the British Museum for several years with the aim of "compiling an anti-Semitic history of Anglo-Jewry".

After the war, the museum continued to collect from all countries and all centuries: among the most spectacular additions were the 2600 BC Mesopotamian treasure from Ur, discovered during Leonard Woolley's 1922–34 excavations. Gold, silver and garnet grave goods from the Anglo-Saxon ship burial at Sutton Hoo (1939) and late Roman silver tableware from Mildenhall, Suffolk (1946). The immediate post-war years were taken up with the return of the collections from protection and the restoration of the museum after the Blitz. Work also began on restoring the damaged Duveen Gallery.

New public face (1950–1975)

In 1953, the museum celebrated its bicentenary. Many changes followed: the first full-time in-house designer and publications officer were appointed in 1964, the Friends organisation was set up in 1968, an Education Service established in 1970 and publishing house in 1973. The British Museum Act 1963 introduced administrative reforms. It became easier to lend objects, the constitution of the board of trustees changed and the Natural History Museum became fully independent. By 1959 the Coins and Medals office suite, completely destroyed during the war, was rebuilt and re-opened, attention turned towards the gallery work with new tastes in design leading to the remodelling of Robert Smirke's Classical and Near Eastern galleries. In 1962 the Duveen Gallery was finally restored and the Parthenon Sculptures were moved back into it, once again at the heart of the museum.

By the 1970s, the museum was again expanding. More services for the public were introduced; visitor numbers soared, with the temporary exhibition "Treasures of Tutankhamun" in 1972, attracting 1,694,117 visitors, the most successful in British history. In the same year the British Library Act 1972 was passed, separating the collection of manuscripts and printed books from the British Museum. This left the museum with antiquities; coins, medals and paper money; prints and drawings; and ethnography. A pressing problem was finding space for additions to the library which now required an extra 1+1⁄4 miles (2.0 km) of shelving each year. The government suggested a site at St Pancras for the new British Library but the books did not leave the museum until 1997.

Great Court emerges (1975–2000)

The departure of the British Library to a new site at St Pancras, finally achieved in 1998, provided the space needed for the books. It also created the opportunity to redevelop the vacant space in Robert Smirke's 19th-century central quadrangle into the Queen Elizabeth II Great Court – the largest covered square in Europe – which opened in 2000. The ethnography collections, which had been housed in the short-lived Museum of Mankind at 6 Burlington Gardens from 1970, were returned to new purpose-built galleries in the museum in 2000.

The museum again readjusted its collecting policies as interest in "modern" objects: prints, drawings, medals and the decorative arts reawakened. Ethnographical fieldwork was carried out in places as diverse as New Guinea, Madagascar, Romania, Guatemala and Indonesia and there were excavations in the Near East, Egypt, Sudan and the UK. The Weston Gallery of Roman Britain, opened in 1997, displayed a number of recently discovered hoards which demonstrated the richness of what had been considered an unimportant part of the Roman Empire. The museum turned increasingly towards private funds for buildings, acquisitions and other purposes. In 2000, the British Museum was awarded National Heritage Museum of the Year.

British Museum today

Today the museum no longer houses collections of natural history, and the books and manuscripts it once held now form part of the independent British Library. The museum nevertheless preserves its universality in its collections of artefacts representing the cultures of the world, ancient and modern. The original 1753 collection has grown to over 13 million objects at the British Museum, 70 million at the Natural History Museum and 150 million at the British Library.

The Round Reading Room, which was designed by the architect Sydney Smirke, opened in 1857. For almost 150 years researchers came here to consult the museum's vast library. The Reading Room closed in 1997 when the national library (the British Library) moved to a new building at St Pancras. Today it has been transformed into the Walter and Leonore Annenberg Centre.

With the bookstacks in the central courtyard of the museum empty, the demolition for Lord Foster's glass-roofed Great Court could begin. The Great Court, opened in 2000, while undoubtedly improving circulation around the museum, was criticised for having a lack of exhibition space at a time when the museum was in serious financial difficulties and many galleries were closed to the public. At the same time the African collections that had been temporarily housed in 6 Burlington Gardens were given a new gallery in the North Wing funded by the Sainsbury family – with the donation valued at £25 million.

The museum's online database had nearly 4,500,000 individual object entries in 2,000,000 records at the start of 2023. In 2022–23 there were 27 million visits to the website. This compares with 19.5 millions website visits in 2013.

The museum received 6,440,120 visitors in 2025, making it the second most popular attraction after the Natural History Museum.

A number of films have been shot at the British Museum.

Director

The British Museum is a non-departmental public body sponsored by the Department for Culture, Media and Sport through a three-year funding agreement. Its head is the Director of the British Museum. The British Museum was run from its inception by a 'principal librarian' (when the book collections were still part of the museum), a role that was renamed 'director and principal librarian' in 1898, and 'director' in 1973 (on the separation of the British Library).

Trustees

A board of 25 trustees (with the director as their accounting officer for the purposes of reporting to Government) is responsible for the general management and control of the museum, in accordance with the British Museum Act 1963 and the Museums and Galleries Act 1992. Prior to the 1963 Act, it was chaired by the Archbishop of Canterbury, the Lord Chancellor and the Speaker of the House of Commons. Of the 25 trustees, 15 are appointed by the Prime Minister, one by the Crown, four by relevant industry bodies, with the remaining five appointed by other trustees. The board was formed on the museum's inception to hold its collections in trust for the nation without actually owning them themselves, and now fulfil a mainly advisory role. Trustee appointments are governed by the regulatory framework set out in the code of practice on public appointments issued by the Office of the Commissioner for Public Appointments.
