The British Museum stretches over 14 acres and has over 90 rooms, some with permanent exhibits including the Egyptian mummies as well as coins and medals dating from the Roman period. The museum also has a range of prints and drawings from Botticelli to Bonnard. In the later part of 2000 the museum underwent various significant changes. A whole new wing has been added, with many more exhibits and with the museum still being free of charge millions of people come and marvel.
