Allowed to climb through, over, and around most of the middle castle for 5 Euro. Museum too, but I didn't bother.
Lower castle in town. They were having a renaissance festival with jousting and events.
Top castle farther up the mountain.
Church farther up the mountain.
Park around the castle was free
Two moats and two draw bridges.
After the clouds lifted, I could see all three from my rented house.
