Mechelen town hall on the Grote Markt consists of two parts: the cloth hall with unfinished belfry and the Palace of the Great Council. The cloth trade went into decline in the 14th century and there wasn't the money to complete the building. For two hundred years the belfry was no more than a shell, until it was eventually provided with a temporary roof in the 16th century. The belfry is now a UNESCO world heritage site. On the right of the belfry you can see the oldest part of the town hall, the remains of the earlier cloth hall. On the left is the Palace of the Great Council. The Great Council never actually met here, because this wing was only completed in the twentieth century in accordance with the original sixteenth-century plans of the then leading architect Rombout Keldermans. The interior of the Town Hall is well worth seeing.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.
