Cesis Castle is one of the most substantial medieval ruins in the Baltics. The Livonian Order began construction in the early thirteenth century and added to the fortress over several centuries; at its height it was one of the most powerful castles in the region. The ruins are extensive, with towers, walls, and cellars still standing above ground.
The museum visit is well designed. Visitors are given lanterns to light their own way through the darkened interior — since the tower has no electric lighting — which gives the experience an unusual atmospheric quality. The adjacent 19th-century manor house (Jaunā pils) holds a regional history museum covering Latvia's complex history under the Livonian Order, the Polish-Lithuanian Commonwealth, Sweden, Russia, and the independent republic. Entry to the castle and manor museum is combined; allow at least two hours.
