The largest market place in Thuringia is at Stadtilm. The size of 10,635 sqm was confirmed when the MDR-Thüringen did a survey in public on 1 November 2011.
Every year on the last weekend in August, the Stadtilm festival takes place on this market square.
The market and its adjacent streets become the cultural centre for a summer weekend every year. Jointly organised by clubs and tradesmen of the city, this festival is a highlight for the Stadtilm people and their guests. There is a vast variety of food, drink and entertaining stage shows as well as fun and games for the children. In addition to the well proven programme there is something new to hear or to see every year.
The city is at the meeting of the former trade routes between Ilmenau and Weimar as well as Erfurt and Rudolstadt.
