The Lutheran church of St. Catherine was built between 1788-1793. It is named after Empress Catherine II, who donated 28 000 silver roubles to the construction. The classicist-style building is a one naved church with large arched blind windows.
In the course of renovation in 1879, the spire received a new helmet and a clock with four faces. Supposedly architect Christoph Haberlandt made the design of the church. The altarpiece depicts Christ on the cross and is subject to protection by the state as a heritage of culture.
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.
