Antskog ironworks, one of the oldest industrial sites in Finland, was established in 1640. The heyday of Antskog was in the 17th century, when Pohja town became a center of iron manufacturing in Finland. Industrial buildings were mainly destroyed in the Greater Wrath (1714-1721) and it caused the financial downturn. The ironworks went bankrupt couple of times.
The next upswing was in the 1860s, when Antskog started to produce copper. Antskog started also a textile business in the 19th century. The industrial story ended in 1959. Today there are about 120 people living in the ironworks area. Many summer events are also held in Antskog. The ironworks area and local wooden church (built in 1766) are open to the public.
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.
