Danube port town on the Slovak-Hungarian border
Komárno is a Danube river port in southern Slovakia, facing its Hungarian twin town Komárom across the water. It has a large historic fortress system and a shipyard.
Long a strategic Danube fortress guarding the river, the town was split in two when the post-1920 border followed the Danube. Its bastioned fortifications are among the largest in central Europe.
