The Untersee, with its German and Swiss sides, forms a very pleasant landscape for cycling. Small, pretty villages with well-preserved historical places and buildings. The location on the Untersee allows for very varied views at all times of the day and in all weather conditions.

The Untersee, with an area of around 62 km², is the smaller of the two lakes of Lake Constance. Of this, 47 km² belong to Germany (Baden-Württemberg), and the remaining 13 km² to the Swiss cantons of Thurgau and Schaffhausen. There are three interconnected lake sections: Gnadensee with its Markelfinger Winkel in the northwest, Zeller See in the west (all in Germany), and Rheinsee in the south (in Germany and Switzerland). Its main inflow is the Seerhein and its only outflow is the Hochrhein. Source: Wikipedia

The historic town hall of Stein am Rhein was built and renovated in several phases. The first phase took place between 1539 and 1542 when the original building was constructed. Later, in 1746, the truss construction was added. Over the years, the town hall has also served as a cloth, grain and department store. In 1900 it was renovated and given its current appearance with a bay window and impressive paintings.

The most striking building with great murals. The town hall was built in 1539-1542, the half-timbered construction in 1745/46. For a long time it also served as a cloth, grain and department store. It got its present form in 1898-1900. At that time the market hall was closed and the bay window and the paintings were attached.
