Katova Bastion is a historic fortress structure. It is one of the few remaining parts of the medieval fortifications that originally surrounded the old town of Košice.

The bastion was built in the 15th century as part of the fortification system around Košice. Bastions were angular projections in the city walls used for flank protection and fire positions.

After serving a defensive purpose for centuries, the bastion began to fall into ruins. It underwent extensive archaeological excavations and reconstruction work in the 1980s to stabilize and restore it.

Today it houses a small historical exhibition telling the story of the bastion and Košice’s fortifications. Artifacts found during the excavation are also on display.

As one of the best preserved remnants of Košice’s medieval walls, Katova Bastion gives visitors an idea of the city’s defensive structures from centuries past. It’s considered an important historical and architectural landmark.
