The town hall in Vilnius was mentioned for the first time in 1432. Initially it was a Gothic style building, and has since been reconstructed many times. The current Vilnius Town Hall was rebuilt in neoclassical style according to the design by Laurynas Gucevičius in 1799. It has remained unchanged since then. Its Gothic cellars have been preserved and may be visited. Nowadays it is used for representational purposes as well as during the visits of foreign state officials and rulers. The Town Hall Square at the end of the Pilies Street is a traditional centre of trade and events in Vilnius.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.
