It is located along the southwest rampart of the Upper Town, in the vicinity of the Pobednik monument and the "King's Gate". An underground object existed during the mediaeval period and is referenced by Constantine of Kostenets during the rule of Despot Stefan Lazarević, in the first half of the 15th century. It apparently was a dungeon as it was mentioned during the 1456 Siege of Belgrade when 30 Hungarian conspirators died in it after their scheme to let the Turks into the fortress and surrender the city to them was thwarted.

Main sources were two large rivers, Danube and Sava, but as Belgrade was quite often under siege or a battleground, it wasn't practical as the rivers would become unreachable during the sieges so they searched for an alternative. Within the scopes of a massive construction and reconstruction of Belgrade in the Baroque manner, from 1717 to 1731 a present facility was dug and a complex wooden mechanism was installed to lift the water up from the pit of . It was designed by Balthasar Neumann. Austrians originally intended to dig a proper water well. They descended to , which is below the water level in the Sava, but found no water and actually hit the impervious rock layer. Then they decided to adapt it into the cistern and to conduct all surface water into it. The mechanism was manually operated, worked on the lever principle and had 12 segments, or
