Rätia Ampla Castle in Riom The Romans already had a settlement in Riom. In the early Middle Ages, a royal court developed. Following the episcopal bailiffs, the land bailiffs lived in what was then one of the largest castles in the canton of Graubünden. After the village fire in 1864, all the wood from the fortress was used to rebuild the village. Until 1977, when a roof was rebuilt, the castle eked out a miserable existence as a ruin. Today's theater house houses Graubünden's largest theater and cultural festival. The Origen Festival takes place every summer in July and August. Rätia Ampla Castle in Riom was probably built around 1250. It quickly changed hands from the old lords to the Bishop of Chur. In 1552, the valley was bought free from episcopal rule. The castle was used as a conference venue and as a prison. Text / Source: Tourism Savognin Bivio Albula AG, Stradung 42, 7460 Savognin https://www.valsurses.ch/de/excursions/burg-riom
