🏺 The British Museum

The British Museum is one of the world's greatest museums and holds approximately 8 million objects spanning two million years of human history. Free entry. Unmissable highlights include the Rosetta Stone (196 BC, key to deciphering Egyptian hieroglyphics), the Elgin Marbles (Parthenon sculptures), the Egyptian mummies, the Lewis Chessmen, and the Sutton Hoo helmet. The Great Court — a stunning glass-roofed courtyard designed by Norman Foster — is spectacular on its own.
