Kazdanga Castle and its complex belonged to the powerful Kurzeme barons Mantteuffel. The castle was built in 1800–1804 following Classicism style according to drawings of architect Johan Georg Berlitz. Kazdanga Castle and the manor is an acknowledged example of Classicism style in Kurzeme. Its design and planning bear resemblance to the Mežotne castle.
Stone bridge over Alokste River is guiding the way to the castle. On the other side of the river, several smaller buildings belong to the manor complex – servants’ house, stables, barn and a steward house. The nearby Cavaliers House shows off its well-preserved interior design, including the baroque staircase and ornamental parquet flooring. Manor complex includes the 196 ha Kazdanga Park, which is one of the largest and most dendrologically diverse parks in Latvia.
