A battery here refers to a number of cannon which are mounted in emplacements which are protected from the front but open at the back.
All adults and children will find something of interest on our 9.5 ha large fortress. You should plan at least two hours for a tour of the fortress. During a guided tour you will also be able to access the 400-year old lower basement and the underground casemates.
Casemate - ital. casa matta (covered house) – cannon-proof fortress rooms.
