Good spot for taking a break or escaping a sudden storm! There's some places to sit, as well as an overhanging roof where you can hide from the rain :)

There's so many great views around the lake, and this is one of them! On a clear day, you can see very far in the distance. But even with less-than-perfect weather, there's still a lot of natural beauty to enjoy.

Colloquially, this bridge is called "Ganggelibrugg" because it sways slightly (ganggelet) due to its light construction.

The baroque old town boasts sights such as the town hall, built between 1747 and 1750, with its rich Rococo decorations, and the 14th-century Church of St. Pelagius. The Thur Bridge, built in 1487, is one of the most important late medieval bridges in Switzerland. In the 9th century, Bischofszell was given the name Episcopalicella by its founder, Bishop Salomo. This translates as "the bishop's cell." Bischofszell Castle was the bishop's castle and dates back to the 13th century.
