Komarno | Slovakia

Komárno functions as the primary cultural and administrative center of the Hungarian minority in Slovakia and a vital river port on the Danube. Situated at the confluence of the Váh and Danube rivers, it serves as a specialized hub for shipbuilding, water transport, and cross-border trade. It is defined by its massive 16th-century fortification system-the largest in the former Austro-Hungarian Empire-and its unique European Place architecture.

Historical Timeline

The city originated as a Roman outpost on the Limes Romanus (Brigetio). The primary era of governance was established in 1265 with the granting of royal town privileges. The primary event shaping its modern identity was the 1920 Treaty of Trianon, which split the historical city into two: Komárno (Slovakia) and Komárom (Hungary). Historically, it was the only fortress in the region that was never conquered by the Ottoman Empire.
