Schloss Arbon

Arbon, Switzerland, Switzerland

---

Schloss Arbon is a medieval castle in the town of Arbon on Lake Constance in Canton Thurgau, Switzerland, with roots tracing to a Roman fortress called Arbor Felix from around 250 AD and an early Frankish structure mentioned in 720 AD under St. Gallen Abbey control.

Rebuilt in the 13th century with a sturdy residential tower featuring 3.2-meter-thick walls and Romanesque fireplaces, it was expanded into its current U-shaped form around 1515-1520 by Bishop Hugo von Hohenlandenberg before serving industrial purposes like silk weaving and machinery experiments by the Saurer family.

Now a Swiss heritage site of national significance housing the Historisches Museum Arbon since 1967, it displays 5,500 years of local history from Stone Age lake dwellings to industrialization, complete with Saurer vehicle exhibits and panoramic lake views.
