There may have been two or three wooden churches in Kökar since the last half of 14th century. During the 16th century a Franciscan monastery was founded on Hamnö island. This place became a spiritual and cultural centre for the entire archipelago.
Today the ruins of monastery share their site with current Kökar's church, which is probably third in this place. It was built between 1769 and 1784 in charge of Antti Piimänen (he died before church was completed). Stones of previous monasteries were used in the construction. In the chapel beside the church are archaeological excavations on Hamnö.
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.
