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:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
