Helfenberg Castle Ruins

Highlight • Castle

A ruin from the early Middle Ages, nothing unusual, but still worth a little detour if you walk past it on the hiking trail. (The ruin is about 100 meters from the path.) Inside the ruin walls there is a small barbecue area under a large shady tree and a small meadow where you can linger and relax. In addition, you will be rewarded with a beautiful view all around due to the elevated location. During our visit, a toilet was set up in a small wooden house for urgent needs.

Is actually only worth it if you are there anyway. The best thing is the view from the opposite slope.

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.

What you learn on a tour of the castle: After Napoleon's fall, his stepdaughter, the Dutch Queen Hortense, bought the Arenenberg castle estate in 1817 and made it her residence in exile. She renovated and furnished the magnificent salons in style. She brought her nine-year-old son Louis Napoléon with her from France, who later became the last emperor of France under the name Napoleon III. His wife, Empress Eugénie, expanded the castle to include additional salons before donating the property to the canton of Thurgau in 1906.
