The neoclassical church of Askainen was built by the owner of Louhisaari Manor, Governor-general Herman Claes'son Fleming in 1653 as the chapel church of Louhisaari Manor. It’s one of the rare stone churches in Finland built after the Reformation in the 17th century. The belfry was erected in 1772–1779. There is a funeral chapel of the Mannerheim family in the cemetery.
The Askainen noblemen's church is part of the oldest tourist route in Finland, the Seven Churches Tour, together with Raisio, Masku, Nousiainen, Lemu, Merimasku and Naantali. Finnish National Board of Antiquities has named the church and near Louhisaari manor as National Built Heritage.
The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
