St Michael's Fortress
The fortress above Sibenik's old town, rebuilt in 2014 with a stage inside its walls.
Updated 30 August 2026
St Michael's stands on the rock directly above Sibenik's old town, the oldest of the town's four fortresses, recorded from the medieval period and rebuilt repeatedly - it was badly damaged in 1663 when lightning hit the powder magazine. It stood ruined for a long time and was restored between 2012 and 2014, with an open-air stage and seating for around a thousand built inside the walls, so it now works as a summer venue with the town, the channel and the islands below the audience. The walls and terraces are open through the day outside performances, and the view over the roofs to St James's cathedral is the reason most people climb.
