Louhisaari Manor is a baroque mansion dating to 1655, located in Askainen near Turku in southwestern Finland. The manor stands as one of Finland's finest examples of 17th-century palatial architecture, with its elegant main building surrounded by an English landscape park. Historically, the estate belonged to the Fleming family and later became the birthplace of Carl Gustaf Emil Mannerheim, Finland's military leader and sixth president. Today, visitors can explore the authentically furnished rooms reflecting various interior-decoration styles from the 17th to 19th centuries, with the festive floor and service floor preserved in original 17th-century style. The manor opened to public access in 1967 and remains an important cultural monument showcasing Finland's architectural heritage.
