Burg Lagenberg

Burg Lagenberg in Laax is a ruined medieval fortress in the Surselva region of the Swiss canton of Graubünden. Historical sources also call it Langenberg, and in Romansh it is Cuolm Liung. Today it is a quiet hiking and mountain-biking objective above the Anterior Rhine valley.

What was Burg Lagenberg?

Around 1300, Laax formed the centre of the Herrschaft Laax together with the Langenberg stronghold and the Marcau market ground. The same area was the hub of the league of free people above the Flimserwald. A Habsburg bailiff (Vogt) lived in the castle. His duties were to hold court and to protect the annual fair.

Where was the fair held?

The market took place around St. Gall's Day on the Marcau meadow, south of the castle, beside the route toward the Lukmanier Pass. Merchants from Lugano attended, which shows that Laax sat on a trading link between the northern and southern Alps.

What happened later?

From 1342 the free people of the district were held in pledge by the Counts of Werdenberg. The sources we used give neither a construction date for the castle nor the time it was abandoned.

What can you see today?

The site lies at about 1,100 m above sea level. It is a ruin, and visitors report an information board on the hill just before it. Read it before you walk around the remaining walls.

How do you get there, and when should you go?

The ruins are in the municipality of Laax. Komoot lists the place for hiking and mountain biking, and one suggested route is a loop of roughly 10.5 km starting in nearby Falera. The snow-free months are best, when trails are dry. In winter Laax is dominated by skiing and the ruin is harder to reach.
