Chillon Castle in Switzerland is renowned as the world's most beautiful prison

From Geneva to Montreux, the journey is a picturesque scene. There are many historical and cultural sites left from the Middle Ages in Switzerland, and we made a special trip to visit the most famous medieval water castle built on the rocks of Lake Geneva—Chillon Castle. It is acclaimed by the public as one of the 'Top 10 Castles in Europe' and 'the world's most beautiful prison'. The British poet Byron left his signature on the stone pillars of the castle, and his work 'The Prisoner of Chillon' adds a cultural hue to Chillon Castle. Due to its very ancient history, people can no longer accurately trace the origins of Chillon Castle. The earliest written records of Chillon Castle that have been found date back to the 11th century. Chillon Castle guards the strategic pass of the Alps and is a military fortress, with defensive arrow slits, gun ports, cannon ports, and watchtowers on its walls. Inside the castle, there are many secret passages and mechanisms, up and down, like a labyrinth. Under the guidance of a professional tour guide, we visited all the currently open areas, where a large number of medieval relics are displayed. Each indoor space within the castle is not very large, but the areas are clearly defined, including the kitchen, wine cellar, bedroom, duke's residence, bathroom, heraldic hall, scriptorium, parliament building, chapel, treasure vault, underground prayer room, torture chamber, prison... Picture 10 is the royal privy, which leads directly into the lake. I looked down and actually felt a bit of vertigo~
