Tržan Castle in Modruš

The stone walls and bastions of Tržan Castle extend across a ridge at 670 meters elevation, overlooking ancient trade routes between the Adriatic and Pannonia.

The castle served as the main stronghold of the Frankopan noble family from 1193 to the mid-16th century, maintaining control over regional trade and administration.

The castle walls display a distinct fishbone construction pattern that demonstrates the advanced building techniques of medieval Croatian and Venetian craftsmen.

The castle ruins stand within the Josipdol Municipality of Karlovac County, requiring sturdy footwear and physical preparation for the uphill access path.

Despite numerous Ottoman attacks in the region during the 15th century, including the destruction of Modruš town in 1493, the castle remained unconquered.
