The Town Hall (Rathaus) is the oldest building in the Market Square. It was built in 1435, and an astronomical clock was installed on it in 1511. It is made upon the project of Johannes Stöffler, a professor of mathematics and astronomy of Tübingen. At first, the clock was placed at the level of the third floor, but in 1849 it was moved to the center of the building’s tapered roof. The clock has three faces: a regular, telling the time, an astronomical with three hands, which count the months, years and laps of 18 years, and the third very small, which shows the moon phases. Despite its considerable age, the clock is still working properly.
Colorful paintings on the building face attract attention, although they were made relatively recently, in the late XIX century. A small wooden statue of bacchante, a follower of the god of wine Bacchus, is installed on the south-west corner of the Town Hall. Her presence is a tribute to winemaking traditions of Tübingen.
