The structure was built in the 17th century by the Polish-Lithuanian Commonwealth to protect the city from attacks by sea.
The fortress is made up of several buildings, including a large central tower, barracks, and a chapel. The tower is the most prominent feature of the fortress, standing at over 30 meters tall. It was originally used as a watchtower and as a place to store weapons and ammunition.
