About this place
Burg Grünenfels is a ruined medieval castle hidden in the forest above the village of Waltensburg/Vuorz in the Surselva region of the Swiss canton of Graubünden. The village is now part of the municipality of Breil/Brigels. Grünenfels was one of four fortresses that once stood around Waltensburg, together with Jörgenberg, Kropfenstein and Vogelberg.
Who built and held Grünenfels?
Through the 13th and 14th centuries the castle was home to the Grünenfels family, knights in the service of the Bishop of Chur. The earliest known member, Konrad, appears in records in 1257. In 1278 the brothers Albert and Heinrich joined Walter von Vaz and other nobles in a quarrel with Disentis Abbey. Albert is last recorded in 1321. After that the castle passed through his daughter Margarethe to the family of her husband, Heinrich von Montalt. The Swiss Historical Lexicon points to the 1984 Burgenbuch von Graubünden for further detail.
What is left to see?
The ruin sits deep in woodland on a spur between two gorges, one of which separates it from Waltensburg and its well-known medieval church. You will find the remains of a tower and a surrounding wall. The south-east corner still rises about 8 m, though the masonry is badly weathered and unstable. This is a place for those who enjoy wild, overgrown ruins rather than visitors who expect signage and facilities.
How do you plan a visit?
Grünenfels is not the target of the official themed trails. The well-known loop from the village leads to the neighbouring Jörgenberg ruin (Munt Sogn Gieri): 3.6 km, about an hour, starting at Cadruvi square by the post office in Waltensburg. Use it as your base if you want to combine several castles in one outing. Wear sturdy footwear and keep your distance from the standing wall.
