Schloss Lenzburg

You're standing at Lenzburg Castle, high above the old town of Lenzburg. It's one of the oldest and most important castles in Switzerland. The hill beneath your feet is almost perfectly round. It rises about a hundred metres above the plain, yet it's only around two hundred and fifty metres across. People lived up here back in prehistoric times. In 1959, a Stone Age grave even turned up in the car park.
