The New Cēsis Castle (Pils Square 9) was built in 1777 as a residence for Karl Eberhard von Zievers, and it is home to the Cēsis Museum of History and Art, which was opened in 1949.  The building has a neo-Gothic tower decorated with curved arcades and window apertures.  It is one of the first examples of eclecticism in Latvian architecture.  Beginning in 2012, the museum will feature a modern exhibition under the title "Latvia: Symbol of Latvian History."  This will be an interactive exhibition featuring the history of Cēsis and its environs since the era of the Vendians and up to the early 20th century.  There will be sections on the history of the Latvian flag, the lives of the Zievers dynasty, and the family's great contributions toward the development of Cēsis.  The third and fourth floors of the castle are dedicated to temporary exhibitions, and there is a special room there for families and children.  The tower of the castle offers the best view of the Cēsis Castle ruins, the old town, and St John's Lutheran church.

The mansion of Uue-Varbla Manor houses the local history museum which presents local life from the early 20th C and history of Varbla municipality. There is a handicraft workshop in the museum, while old tools and machinery are exhibited in the granary. The mansion in early Classicist style from 1797 is an attraction in itself. Traditional handicraft fairs are held in the grounds in July every summer.
