Billnäs ironworks was founded in 1641 by Carl Billsten. It faced many difficulties during 17th and 18th century. Local peasants destroyed the ironworks already in 1659 because of too heavy taxation. During the Great Wrath Russians occupied and destroyed it again in the 18th century.
Billnäs Ironworks moved to Hisinger family's possession in 1723. Bar hammer workshops with forges and waterwheels, and coal rooms were built to both sides of the rapids in Billnäs Ironworks. Johan Hisinger was especially active in building and developing the Ironworks’ operations. Billnäs manufactured many kind of forge products until 1920, when it was incorporated into Fiskars Corporation (the another ironworks site nearby).
An industrial business ended in Billnäs in the end of the 20th century. Today it’s moved to the use of service industry. Various public events, concerts and exhibitions among others, are organized in the Billnäs Ironworks. In the long run, hotel- and restaurant operations are planned to the area as well as a full renovation of the valuable real estates. The ironworks area is today a well-preserved national heritage. The most valuable building is the great forge from the 17th century.
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.
