Liinmaa Castle

In the Middle Ages, a wooden castle stood at the bottom of Väkkäränlahti Bay, protected by two walls and water. The castle controlled trade and traffic in the Gulf of Bothnia. The castle was used in the 1300s, probably as early as the late 1200s. Queen Margaret I probably sealed the fate of Liinmaa Castle by ordering the demolition of all redundant castles at the end of the 1300s.
