The castle sits on a low ridge directly above town, reached by a short path that climbs through the vineyards. The medieval defensive structure is mostly intact — walls, keep, gatehouse — and the courtyard inside is now used as a summer open-air theatre, which is the main reason most visitors come up.
Even outside festival season the climb is worthwhile for the view down over the red-tiled rooftops, the church, and the river bend. Free to enter the grounds outside performance times.
