In Roman times the Bruckneudorf area was already densely populated, and Villa Bruckneudorf, one of the most important Roman villas to be discovered in Eastern Austria, is a few kilometres to the east. The villa is presumed to be a residence of the imperial family in the autumn of 375 AD. Today impressive ruins remain. Of the magnificent mosaics, more than 300 m² are still preserved. These are located in the Landesmuseum in Eisenstadt.
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.
