It was built in the nineties of the fifteenth century to help defend the town from the rivers, from the western part of the Lower Town to the Nebojsa Tower. This rampart was the weakest, which proved to be fatal for the defence of Belgrade in 1521. By the end of the seventeenth century the Turks started to reconstruct the coastal rampart, which continued during the Austrian occupation as well. The medieval rampart was partly rebuilt, and partly integrated into a new fortification. Inside the rampart there were the Water Gate I and II. The rampart was damaged during the First and Second World War, especially in 1941, when a railway track was widened to improve the transport of the army and its equipment.
