The castles were fortified settlements in which the basic functions of a town were concentrated. They were built on key sites supervising mountain passes and offered their residents and the people of the surrounding area a place of safety in time of war. The limited space and the morphology of the terrain determined the town-planning of the castles and the changes made to the architecture of the houses.
Opened on November 10th, 2000, the gallery presents the defensive system of the Byzantine Empire, the organization of a castle, as well as related everyday life and productive activities inside and outside of its walls. The archaeological material on display comes from various castles in Macedonia, most notably the one at Redina. The subject is supplemented by a video installation on the castles of Macedonia and Thrace.
