Blumenstein Castle is a castle ruin in the Palatinate Forest probably constructed in the first half of the 13th century as part of a line of defensive castles along the Alsatian border. The castle was first mentioned in 1332 in connection with knight Anselm from Batzendorf near Blumenstein. After a feud with the House of Fleckenstein in 1347, the knight was banished from the castle.
About 1350, the counts of Zweibrücken had one quarter of the castle, the House of Dahn owned the rest. Blumenstein castle was probably destroyed in the German Peasants' War in 1525. The ruin passed from the counts of Hanau-Lichtenberg to the landgraves of Hesse, then to the bishopric of Speyer and finally to the state of Rheinland-Pfalz.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.
