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.
La Hougue Bie is a Neolithic ritual site which was in use around 3500 BC. Hougue is a Jèrriais/Norman language word meaning a \'mound\' and comes from the Old Norse word haugr. The site consists of 18.6m long passage chamber covered by a 12.2m high mound. The site was first excavated in 1925 by the Société Jersiaise. Fragments of twenty vase supports were found along with the scattered remains of at least eight individuals. Gravegoods, mostly pottery, were also present. At some time in the past, the site had evidently been entered and ransacked.
In Western Europe, it is one of the largest and best preserved passage graves and the most impressive and best preserved monument of Armorican Passage Grave group. Although they are termed \'passage graves\', they were ceremonial sites, whose function was more similar to churches or cathedrals, where burials were incidental.
