Bomb Proof Barracks built at Europe.  This is now the University of Gibraltar but many of the old features have been faithfully retained.

The building is split into to halves.  Northern part is casemated rooms with a courtyard and perimeter wall.  There are three small caponiers.   The southern half is casemated accommodation.  This section has a looped holed wall around the top, this faces out towards the small beach below.
