Hisarlaka Fortress

Hisarlaka Fortress is a Roman military stronghold near Kyustendil with an irregular polygon shape. The structure contains roughly fourteen towers of different shapes, with two main gates plus additional hidden entrances built into the defensive system.

Romans built this fortress around 400 AD as a defensive stronghold for the region. Ottoman forces later destroyed it after centuries of military use and modifications.

The fortress displays Roman construction methods combining stone and brick in ways that show careful craftsmanship. Visitors can observe these building techniques directly when walking around the walls.

The site is located southeast of Kyustendil and accessible through local roads from the city. Wear sturdy shoes when exploring the grounds, as the terrain is uneven and some walls are partially damaged.

The fortress features a network of hidden entrances built into its defensive walls for discreet movement. These concealed passages allowed occupants to move supplies or evacuate without being seen from outside.
