A historic castle and the country's most visited place, on a small island in Lake Geneva only a few meters from the shore. It was built originally to allow the occupants to extract a toll from people and goods passing between Italy and the rest of Europe on the road north from the St. Bernard pass. The roadway here is wedged between the lake and the cliffs, so there was no way to get around Chillon. The Castle is more famous in modern times for having inspired Lord Byron's poem, The Prisoner of Chillon, based on the true story of François Bonivard, a political prisoner from Geneva who was released in 1536. Byron is said to have carved his name in one of the columns in the dungeon where Bonivard was detained during a few years.
