Chillon Castle is unique due to its location on Lac Léman and is one of the most visited castles in the country thanks to the panoramic views of the surrounding mountains and the lake - no wonder it was also used as a location for the film "The Little Mermaid" in 2018. You can explore a variety of rooms and exhibits, including the Duke of Savoy's chambers, the Chapel of St. George and the dungeon. The castle is open to visit year-round and hosts a variety of events and exhibitions throughout the year, including concerts, art exhibits, and historical reenactments.
