During the Second World War many forts and defense walls were raised to protect Sweden from the invasion of German troops. Parsetjärn Fortification is one of these historical structures. The fort was restored by Dals-Ed Municipality and is frequented by tourists, historians and researchers to gain insight into the defense strategies and plan of the bygone era.References:
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.
