Château de Chillon from the lake. Note the rickety balconies and the latrine chutes visible in the last pic. The door in the second pic is that out which the Savoyard in charge (name of Antoine somethingorother) escaped in 1536 - the Bernese besieged the castle from the land side, but had not posted a watch on the lake side of the castle.
The Bernese subsequently took control and set free their countryman fellow-protestant, a chap named Bonivard who the Duke of Savoy had imprisoned. Years later Byron wrote a poem about him.
