The iron manufacturing in Kauttua started in 1689, when nobleman Lorentz Creutz was granted to establish an ironworks to Kauttua rapids. The ironworks business created an historically valuable industrial village milieu, which is called today as “Kauttua Ruukinpuisto”. In 1907 the ironworks was acquired by Ahlström Oy and it was changed to manufacture paper.
Most of village buildings are from the 19th century. One of the most finest buildings is so called clubhouse (functioning as restaurant today), which was built in 1802. There are also many buildings designed by the most famous Finnish architect Alvar Aalto.
Today the ironworks area is open to the public providing accomodation, conference and restaurant services. There’s also an ironworks museum and guided tours to milieu are available.
The Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
