As we go upstairs we arrive into the Carthusian Gallery which hosts the spectacular collection of present cetaceans skeletons. This collection, one of the most important in Europe, was set by Sebastiano Richiardi during his direction (1871-1891), even though written documents testify that in 1626 some cetaceans finds were already in the Museum. In all, the Museum possesses 53 skeletons, 23 of which are here exposed.
