The best free museums in London
"You could retrace much of human history at the British Museum, which holds a massive eight million objects from around the world. There are sections dedicated to ancient Greece, Rome, Egypt and the Middle East, as well as North America and medieval Europe. Some of the main featured pieces include the Rosetta Stone and the Elgin Marbles, which once adorned the Parthenon in Athens, one of many pieces whose ownership now comes up for debate."
