Aizkraukle Castle (Ascheraden) is the ruins of a medieval castle, located on the right bank of the river Daugava. The castle was built in second half of 14th century by the Livonian Order. From 1334-1480 it was the seat of a Komtur.
In 1559, Aizkraukle was seized by the Poles and in 1577 captured by the Russians. The castle was still standing in 1633, but was in ruins by 1680. Today there are seen remnants of fundament of the castle and up to 5 metres high fragments of one wall. Picturesque ruins serve as a popular local tourist destination.
The castle should not be confused with the Old Aizkraukle Castle (Alt-Ascheraden) - another 13th century medieval castle a few kilometres downstream.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.
