Located just off the eastern shore of the old Croatian town of Sibenik, St. Nicholas Fortress is a fascinating ancient fortress originally built in 1540. It is the only one of Sibenik’s four fortresses to be located at sea and is a UNESCO World Heritage Site. St. Nicholas Fortress is considered to be one of the best preserved examples of historic defence architecture in Croatia, making it a great site to visit for those looking to binge on culture and history while on their holiday.
It was successfully used to protect the city from enemies who would attempt to attack the town by sea, particularly to stop Turkish boats reaching the nearby port. Unlike many fortresses which are built with stone, the walls of St. Nicholas Fortress are made of brick as it was believed that this would be the best material to protect the fortress from incoming cannonball attacks. Only the foundations of the structure are made from stone.
