Fortress of Komárno

The Fortress of Komárno spreads across both banks of the Danube with a network of bastions, walls, and defensive structures on the Slovak and Hungarian sides. The complex includes multi-level fortified buildings and open courtyards that show the scale of the military construction.

Construction started in the 16th century to protect against Turkish invasions, and major expansions happened in the 19th century under Austro-Hungarian rule. These additions made it one of Europe's largest fortress complexes.

The fortress displays Roman stone artifacts in Bastion IV, revealing ancient objects from when soldiers and settlers protected this region. Visitors can see these traces and understand how military presence shaped the area over many centuries.

The site is open year-round and can be explored with guided tours organized by Pro Castello Comaromiensi. It sits on the Danube bank and is walkable from the town center.

The complex was designed to house up to 200,000 soldiers and remained in continuous military use from the 16th century until 2003. What stands out is that it was never captured during all those centuries.
