10 best free London museums for children
"When the British Museum was opened in 1759 it was the first free to enter national museum to be open to the public anywhere in the world. The first exhibits consisted of the collection of physician and naturalist Sir Hans Sloane – ancient coins and medals, books and natural remains. Over the centuries it has become home to the most significant finds made by British explorers, like the Rosetta Stone from Ancient Egypt and the Parthenon sculpture from the Acropolis in Athens."
