Burg Pontaningen

Burg Pontaningen is a castle ruin located near Sedrun in the Grisons region of Switzerland. The main structure consists of a tower with stone walls standing on a mountainside above the Rhine River, with traces of fortification elements including carved ditches.

The castle dates to the 13th century and is linked to the Pontaningen family, whose earliest recorded member was Knight Wilhelm in 1252. The family served the Disentis monastery and eventually faded from historical records.

The name comes from the Pontaningen family who held power in this area. Their fortress shows how local noble families built strongholds to maintain control in the Alpine valleys.

The ruins lie southwest of Rueras near Sedrun and are reachable via a short hiking path. The location sits between the Oberalp Road and the Rhine valley, making access straightforward from the main routes.

The castle is distinguished by a moat cut directly into the bedrock with remarkable precision and care. This technical achievement shows the engineering knowledge that medieval fortress builders possessed.
