During the course of history, Belgrade had two separate docks, on the Sava and on the Danube. The Sava dock was fortified along the western side of the fort and was directly connected with the inner fort and the town commander. The Danube dock was used for trading and reached its full expansion during the 16th and the 17th centuries. The approach docks were neglected and the Danube bank, where harsh winds blew, was no longer suitable for docking and handling ships, so the one on the Sava bank got the priority. Wholesale trading export-import centre had gradually developed by the docks.
In the middle of January 1929, Belgrade and the whole of Serbia were stricken by immense cold. It snowed for several days and the temperatures dropped to below minus 30 degrees Celsius. The river traffic was suspended and the ships were towed into winter storage hangars, where they were kept until the weather conditions improved and the traffic could resume. The winter of 1933 was also very harsh and the Danube was covered with huge piles of ice, making the sailing impossible.
