Wichenstein Castle

Wichenstein Castle is a medieval cave castle, now a ruin, in the municipality of Oberriet in the Canton of St. Gallen, eastern Switzerland, near the village of Kobelwald. It is listed as a Swiss heritage site of national significance.

What is a cave castle?

A cave castle (German: Höhlenburg) uses a natural rock recess as its interior and closes the open side with a wall. At Wichenstein the cave is about 15 metres deep. Its mouth was sealed with a four-storey front wall roughly 2.1 metres thick at the base. The rock covered the back and top, so defence depended entirely on that single wall.

Where is it?

The ruin sits on the eastern flank of the Semelenberg, west of Oberriet, above the Rhine Valley (Rheintal). The coordinates are about 47.327 N, 9.554 E. The surroundings are hilly and wooded, and the castle blends into the cliffs above the valley.

History

According to research, the castle was built in the 13th century, when the cave was expanded for defensive use. It is regarded as the residence of the knights of Wichenstein. The family first appears in a document from 1270, though it is not known whether they built the castle themselves. Over time the stronghold went out of use and became the ruin visible today.

What you will see

The main surviving element is the massive front wall. You enter through a gap in it, and the cave is open to visitors without tickets or restrictions. The ruin impresses mostly through scale: a thick wall set against an overhanging rock makes it easy to imagine how cramped life inside must have been.

Legends

Many folk tales cling to Wichenstein. They tell of robber barons whose ghosts are said to still haunt the walls, and of a treasure guarded by a toad. These stories make good material for children on a family outing.

Getting there and nearby sights
