The Charles Bridge is a famous historic bridge that crosses the Vltava river in Prague. Its construction started in 1357 under the auspices of King Charles IV, and finished in the beginning of the 15th century. The bridge replaced the old Judith Bridge built 1158–1172 that had been badly damaged by a flood in 1342. This new bridge was originally called the Stone Bridge (Kamenný most) or the Prague Bridge (Pražský most) but has been the 'Charles Bridge' since 1870. As the only means of crossing the river Vltava until 1841, the Charles Bridge was the most important connection between Prague Castle and the city's Old Town and adjacent areas. This 'solid-land' connection made Prague important as a trade route between Eastern and Western Europe.
The bridge is 621 metres long and nearly 10 metres wide, resting on 16 arches shielded by ice guards. It is protected by three bridge towers, two of them on the Lesser Quarter side and the third one on the Old Town side. The Old Town bridge tower is often considered to be one of the most astonishing civil gothic-style buildings in the world. The bridge is decorated by a continuous alley of 30 statues and statuaries, most of them baroque-style, originally erected around 1700 but now all replaced by replicas.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.
