Lunkhofen castle ruin

Lunkhofen castle ruin (Burgruine Lunkhofen) stands in the woods above the village of Oberlunkhofen in the Swiss canton of Aargau, in the Bremgarten district. What remains are modest medieval wall stumps of a fortress that history barely mentions, set in an area rich in traces from prehistory through the Roman era to the Middle Ages.

What is this place?

Only fragments of the walls survive, hidden among trees. No written document records the castle's founding, its owners or its abandonment. The Historical Lexicon of Switzerland gives 1386 as the year of destruction, a period of conflict between the Habsburgs and the Swiss Confederation. The Aargau heritage inventory notes that nothing certain is known about the castle's origins.

Researchers associate it with an administrative family that held the steward's office (Meieramt) in Lunkhofen. A link to the Zurich family of Lunkhofen has never been proven.

How was the ruin investigated?

The Swiss Castle Association (Schweizerischer Burgenverein) carried out preliminary work in 1930. In autumn 1933 the Historical Society of the Freiamt commissioned an excavation. Between 1975 and 1980 the walls were uncovered and partly conserved. Today the ruin is listed in the Aargau monument inventory as DSI-OLU006.

What is the historical background?

Oberlunkhofen was the seat of the Kelnhof, the administrative centre of the Lunkhofen manor, which belonged to Murbach Abbey and Lucerne. In 1291 the estates were sold to the Habsburgs, specifically King Rudolf I. The village lies above the right bank of the Reuss valley. A ferry across the river, first recorded in 1160, served the main road between Zurich and Bern until the 16th century.

What else is nearby?

• The Bärhau forest holds a large prehistoric burial-mound cemetery, among the more important in the region.
• A Roman villa was found at a site called Schalchmatthau.
• The Reuss valley, with its river and fields, suits quiet walks and bike rides.

When to visit

The ruin lies in woodland, with no ticket office or opening hours. Spring and autumn are best, when paths are dry and more light reaches the forest floor. Wear sturdy shoes. The site sits at roughly 47.3187 N, 8.3889 E.
