Lotrščak Tower

This squat Romanesque tower guarded the southern gate of medieval Gradec, the fortified upper town of Zagreb, and today anchors one of the city's finest viewpoints. Since the nineteenth century a cannon known as the Grič cannon has fired from the tower every day at noon, a tradition said to help residents synchronise their clocks. Visitors can climb the internal staircase past small gallery spaces to a rooftop terrace overlooking red-tiled roofs and the cathedral spires. The name derives from a bell that once warned of the closing gates.
