The trustees settled on Montagu House in Bloomsbury as a home for the new British Museum, opening it to the public for the first time on 15 January 1759. With the British Museum now established numerous other collectors began to donate and bequeath items to the museum's collections, which were further swelled by large quantities of exhibits brought to England in 1771 by the first voyage of James Cook, by a large collection of Egyptian antiquities (including the Rosetta Stone) ceded by the French in the Capitulation of Alexandria, by the 1816 purchase of the Elgin Marbles by the British government who in turn passed them to the museum, and by the 1820 bequest of the vast botanical collections of Joseph Banks. Other collectors continued to sell, donate or bequeath their collections to the museum, and by 1807 it was clear that Montagu House was unable to accommodate the museum's holdings. In 1808–09, in an effort to save space, the newly appointed keeper of the natural history department George Shaw felt obliged to destroy large numbers of the museum's specimens in a series of bonfires in the museum's gardens. The 1821 bequest of the library of 60,000 books assembled by George III forced the trustees to address the issue, as the bequest was on condition that the collection be displayed in a single room, and Montagu House had no such room available. In 1823 Robert Smirke was hired to design a replacement building, the first parts of which opened in 1827 and which was completed in the 1840s.
