The origin of the historic Wurstkuchl was a small building leaning against the city wall, which served as a construction office during the construction of the stone bridge from 1135 to 1146. When the building, which was celebrated as the eighth wonder of the world at the time, was completed, the construction office moved out and the small building became the "food stall on the crane". The customers of the cookshop were port and construction workers, hence the name »Kranchen«, the word for crane or cranes at the time. There were many port workers because the wealthy commercial patricians of the Free Imperial City of Regensburg used the port intensively for centuries as a transshipment point for goods from all over the world. The hungry construction workers, on the other hand, came mainly from the construction site of the Regensburg Cathedral.
