Arbon Castle, castle in Arbon, canton of Thurgau, Switzerland
Arbon Castle is a medieval fortress in the town of Arbon near Lake Constance. The castle features a U-shaped layout with a substantial tower from the 13th century and thick stone walls that underscore its military purpose.
Arbon Castle was first documented in 720 and stood on the remains of a Roman fortress from around 250. The current structure took shape largely in the 13th century but was substantially redesigned between 1515 and 1520 by Bishop Hugo von Hohenlandenberg.
Arbon Castle served for centuries as the seat of power and administration for the town. Today the place reflects the importance this location held and continues to hold for the local community.
The castle is located in the center of Arbon on Im Schloss street and is easily accessible by car or public transport. You can explore on your own or join a guided tour that explains the artifacts and the building's history.
The castle was deliberately constructed to completely cover the foundations of the Roman fortress beneath it. This hidden architectural layer reveals a fascinating example of how medieval builders integrated older structures into their new designs.
