The British Museum was established on the 7th of June 1753, when King George II gave royal assent to the founding Act of Parliament. It is based primarily on the collection of the Anglo-Irish physician Sir Hans Sloane, who bequeathed around 71,000 objects to the nation for a payment of £20,000.
The British Museum's permanent collection numbers over 13 million objects, though only approximately 50,000, less than one percent of the total, are on public display at any given time.
The Rosetta Stone is a trilingual stela dating to 196 BC that proved key to deciphering ancient Egyptian hieroglyphics. King George III presented it to the British Museum in 1802 following the British victory at the Battle of the Nile, and it remains one of the museum's most visited objects, though Egypt has pursued repatriation claims for its return.
The Elgin Marbles are large marble sculptures removed from the Parthenon on the Acropolis of Athens by Thomas Bruce, 7th Earl of Elgin, while he served as British ambassador to the Ottoman Empire from 1799 to 1803. The British Museum acquired them in 1816 under the British Museum Act 1816. Greece has maintained a long-term repatriation claim for their return.
In 2025 the British Museum received 6,440,120 visitors, making it the second most visited attraction in the United Kingdom. In 2023 it recorded 5,820,860 visits, a 42 percent increase on 2022 and sufficient to make it the most visited tourist attraction in Britain that year.
