History

Koivula Kartano's history dates back to the 16th century. The estate was formed from many small pieces of farmland from the Karnais village by Erik Fleming in 1540. The estate belonged 200 years to the old Fleming family, who owned the Suitian linnakartano in Siuntio. The mansion was called hovi (court) until it was named Koivula 1724. Subsequently in the 1830's the owner Berndt Wilhelm Nordberg named the estate Wilhelmshaven. Nordberg built the Gustavian-style yellow main building in 1832.

In the 1950's, the main building of its current form was hosted by the Forsström family (1877-1982). The top floor, one-storey sides and the main entrance were demolished from the three-story main building. The house was covered with a gable roof, central heating and windows in the 50s.

The Aho family has been living in a mansion since 1984. In 2011, the main building has been converted from a home to a hotel.

The oldest preserved buildings in the courtyard are grain magazine and stone barn, both of which were built in the 1700s.
