Arbon is located in the Swiss Thurgau on a spur-shaped peninsula on the southern shore of Lake Constance not far from the Säntis. The city of Arbon is listed as one of the most worthy of protection areas in Switzerland.

Arbon is rich in cultural sights, the Arbon Castle with its imposing defensive tower and the historical museum is one of the most important. The permanent exhibition spans an arc through 5500 years of exciting settlement history on Lake Constance. In the defensive tower there are exhibition areas that show the everyday life and society of bygone times, the changeable history of Arbon Castle.

A climb to the fortified tower is definitely worthwhile.
