First line of defence of Boka
Arza Fortress was built in the mid-19th century, at the same time as Mamula on the islet of Lastavica and the fortification on Cape Oštro, on the proposal of General Lazar Mamula. The three fortifications together closed the entrance to the Bay of Kotor, as part of the system of the Maritime Fortress of Boka. Externally, Arza is well preserved and has retained its original form.
