Water Town In the mediaeval period, the area to the west and south-west, between the tower and the Sava, was a location of the "Water Town" () settlement, built by despot Stefan Lazarević in the early 15th century. It was known for an open green market and a watermill. The settlement was established above the port of "Donji Grad", one of three which Belgrade had at the time (two on the Danube and one on the Sava). The marketplace was especially known as a fish market, but other goods were also traded: grains, fruits, vegetables, wool, hide, fur and wax. Today it is part of the promenade along the Sava, arranged as a wide plateau with anchored barge-restaurants (splav). Since 2007, the "Fish Fest", an annual festival is held on the location. It is a competition of the chefs from Serbia and surrounding countries in preparing fish courses, like the fish soup or a stew. Other, local types of food are also prepared. The festival is organized like a fair, with agricultural products being displayed for selling, music concerts, workshops, children games, etc. The festival is held in August-September.
