Chillon Castle has been both an outpost and residence of the Dukes of Savoy since its founding in the 12th century. and up to the 16th century. It was built as a fortress on a small rock near the shore of Lake Geneva to protect trade routes between northern and southern Europe. At the end of the XVI century. the castle lost its strategic importance and was turned into a prison. The castle consists of 25 buildings and three courtyards protected by two round walls. In the center of the complex rises a 25-meter main tower, other watchtowers are located in a circle. Each room of the fortress reveals its own part of the history of the castle: here are pompous reception halls for celebrations with giant fireplaces and painted ceilings, and a complex of living rooms for princes and counts, and many utility and prison rooms in the basements. Worthy of attention are the Chapel with a painting of the 14th century, the Celebration Hall with an exposition of weapons and armor, the Knights' and Armorial Halls. Since the beginning of the XIX century. The castle houses a museum to this day. From the top of the tallest tower you can enjoy a beautiful view of Lake Geneva and the Alps.
