Our story starts with one man, Sir Hans Sloane, who lived from 1660 to 1753. He was an Anglo-Irish physician and naturalist from Ulster, working as a doctor and scientist in London. He gathered an astonishing private collection, and the foundation of the whole museum was his collection of 71,000 items, left in his will. In 1753, an Act of Parliament created the world's first free, national, public museum. It opened its doors in 1759 to what the law called all studious and curious persons. Do not picture a casual stroll, though. At first, visitors had to apply for tickets, and visiting hours were limited. The museum began life in Montagu House, a seventeenth century mansion on this very site. From the 1830s onwards, the rules changed and opening hours were extended. Gradually the museum became truly open and freely accessible to all. Today it welcomes more than 6 million visitors a year, and in 2025 the count was 6,440,120. It also no longer holds natural history collections, and the books and manuscripts it once held now belong to the independent British Library.
