The seven permanent Egyptian galleries at the British Museum, which include its largest exhibition space (Room 4, for monumental sculpture), can display only 4% of its Egyptian holdings. The second-floor galleries have a selection of the museum's collection of 140 mummies and coffins, the largest outside Cairo. A high proportion of the collection comes from tombs or contexts associated with the cult of the dead, and it is these pieces, in particular the mummies, that remain among the most eagerly sought after exhibits by visitors to the museum.
