This triumphal arch was constructed in 1991 on what was once a very significant passageway to Switzerland by the sculptor Peter Lenk. Lenk also sculpted Imperia at the Constance Harbor.
The arcs and fountain showcase around 30 bizarre sculptures and reliefs. Most of them show different types of people, most of them are holding a steering wheel or sitting on a motorcycle or in a car.
The most notable sculptures include what seems to be a group of barely dressed people in a bath, pigs with human faces, driving babies, monkeys, and many more.
