Koerich Castle ruins is one of the castles in the so-called Valley of the Seven Castles. Standing on level ground in the valley of the stream of Goeblange, the castle's impressive keep and external walls blend harmoniously with the Baroque church and the old houses in the centre of the village.
The Grevenschlass, now known as Koerich Castle, was built by Wirich I, Lord of Koerich and Seneschal of Luxembourg at the end of the 12th and beginning of the 13th century in late Romanesque style. It was expanded in 1304 by Godefroid of Koerich who gave it a more Gothic appearance. The keep, now 11 m tall, was certainly much higher when it was built. With a base measuring 12 by 11.6 m and walls up to 3.5 m thick, it is one of the most impressive in the entire region. A spiral staircase inside one of the walls provided access to the different floors.
Surrounded by a moat, the castle originally had a fortified entrance with a portcullis. From 1380, Gilles of Autel and Koerich converted the stronghold into a more comfortable residence by building two 12-m towers at either end of the south wall. The south-western tower which still stands, houses a chapel on the ground floor. In 1580, the new owner Jacques de Raville made further changes, demolishing part of the property and adding two Renaissance wings. The stately fireplace on the first floor and large rectangular windows testify to the castle's palatial splendor at the time. The south wing was again altered in 1728, this time with Baroque additions.
After the death of the Ravilles in the second half of the 18th century, the castle started to fall into ruin owing to lack of maintenance. In 1950, Pierre Flammang, the last private owner, carried out some essential structural repairs before the castle finally came into the hands of the State. Although major repairs are still in progress, the site can be visited free of charge.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
