Petrovaradin Fortress, the symbol of the town which has long been known as the Gibraltar of the Danube, is perched on the right bank of the Danube River overlooking Novi Sad.

It represents the unique fortification construction of that time in Europe. It stretches at 112 acre, it has four levels and 16 kilometers of underground tunnels with a constant temperature of 12 ° C. It has always been an attractive location, as evidenced by numerous archaeological layers, as well as the representation of all cultures, from the Paleolithic to the present day. Even in Roman times the Cusum fortress existed there.
The Fortress consists of the Upper and Lower City, namely the fortress with one of the most famous landmarks of both the fortress and the city of Novi Sad, the Clock Tower. This baroque tower is famous because the large hand indicates the hour while the small hand indicates the minute.
