Bischofstein Castle

Bischofstein Castle (German: Burgruine Bischofstein) is a ruined medieval hill castle near Sissach in the Swiss canton of Basel-Landschaft. Its walls crown the Chienberg ridge at roughly 698 m above sea level, right on the boundary between Sissach and Böckten. The site is classed as a cultural property of national significance.

What is the history of the castle?

The Lords of Eptingen, a noble family from the Basel region, built the castle around 1250. They named it after the prince-bishop of Basel, their feudal overlord. Records confirm the bishop's overlordship from the early 14th century, and family members styled themselves "of Bischofstein".

An earthquake in 1356 wrecked the fortress, and it was never rebuilt. During the 15th century its estates changed hands several times and were split among neighbouring villages. In 1570 sovereign rights passed to the city of Basel.

What can you see today?

Excavations in 1937 and 1938 uncovered the layout of the whole complex. You can make out a curtain wall with two gateways, a massive round keep in the centre and a rectangular residential hall on the west side. Archaeologists also found service buildings and a hall in the southern part, plus two cisterns. A rock drop protects one flank, and ditches cover the remaining sides.

People used this hill long before the castle. Finds include Neolithic and Hallstatt-period objects and traces of a fortified settlement from the late Bronze Age.

Are there other ruins nearby?

Yes. About 100 m away stand the remains of Itkon, also called Hinterer Bischofstein. It dates from the 12th century and is older than its neighbour, so one short walk takes you past two castles from different eras.

How do you get to Bischofstein?

Hiking trails lead to the ruin from Sissach and from the Sissacherfluh ridge. The route runs through forest and pasture typical of the Jura, so wear proper walking shoes. The train from Basel to Sissach takes about half an hour, and you continue on foot.

When is the best time to visit?

Late spring to autumn, when paths are dry. There is no entrance fee. Bring water and snacks, as the hilltop has no café.
