Chapelle Saint Théodule, Lake of Gruyère
The Sainte-Théodule chapel is located on the site of the ancient medieval town of Pont-en-Ogoz. The chapel, like the castle towers, was built in medieval times around the 13th century, and at the beginning of the 15th century, it was abandoned. In 1948, with the construction of the Rossens dam, the site was flooded and became an island in the Lake of Gruyère.
