Estavayer’s castle (1285–90), home to the prefecture and police station, cannot be visited but its ramparts can be strolled. Ask the tourist office for its Circuit des Remparts brochure that maps out a 1½-hour stroll along the original 40m-long and 35m-wide rectangle interspersed with 16 gates and turrets galore. The largest tower, 32m-tall Grand Tour, could only be accessed via a door that stood 9m above ground level and was reached by a drawbridge in medieval times.
