The wharf extended at the outer side of the north-eastern rampart, from the Nebojsa Tower. It dates back to the period of the rule of despot Stefan Lazarevic. Near the wharf, there was a custom-house and fish market. During the Austrian reconstruction of the Fortress, the wharf was turned into a closed naval port, which was connected with the River Danube by a channel. As the Turks regained power over Belgrade, the channel was blocked with a special gate, which closed with iron bars. The remains of the wharf were visible until the end of the nineteenth century.
