This splendid tower fortification is part of Dutch military heritage and the New Dutch Water Line.
Changing exhibitions are held inside the fort, but the structure is also an artwork unto itself. The dome, for instance, which keeps rainwater out, consists entirely of glass slates developed in the glass workshop of the National Glass Museum.
