Maribor castle, which boasts several constructional and style periods, was built by Emperor Friderik III between the years 1478 and 1483 for the purpose of fortifying the north eastern part of the town wall. The castle was in the course of time changed into a rich feudal residence.
The main room in the castle is the Festive Hall. The hall has rich interior furnishings with pictures of the artistic Quadri family and Laurenzo Laurigo. On the oval ceiling there is the picture of a battle between Christian and Turkish soldiers, which was painted by Johann Gebler from Graz in 1763.
The Baroque stairway was built between 1747 and 1759 and the Loretto chapel between 1665 and 1675.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.
