Vista from the top of Lotrščak Tower (Kula Lotrščak)
Lotrščak Tower is a 13th-century fortified tower located in Gradec (Upper Town). The observation deck at the top offers one of the best 360° panoramic vistas across the historic rooftops of Zagreb and the Lower Town. Every day at noon, the famous Grič cannon (Grički top) is fired from the tower.
