The impressive Castel S. Angelo, dominating Tiber's right bank, hosts a remarkable museum with a collection of weapons, sculptures, paintings and objects linked to the history of the castle.

Erected in 125 by emperor Hadrian, Castel S.Angelo became a castrum (a fortress) under Onorio in 403 and was lately the seat of some papal apartments, too.

The visit to the museum is subdivided into 6 levels: it begins with the Roman Atrium and the Chapel of the Condemned, and continues with the Visiting Rooms and the Prisons, before getting to the third level with the Yard of the Angel and Clement VIII Rooms. Subsequently, it goes on with the Archaeological Gallery, the Library and, eventually, the Terrace of the Angel.

The museo di Castel S.Angelo was founded in 1925 and hosts several collections, partly coming from private donations. Worthy of mention are the beautiful ceramics, a collection of Italian army weapons, the portrait of emperor Hadrian and the 15th century wooden Lamentation over the Dead Christ.
