Koerich () is a commune and village in western Luxembourg. It is part of the canton of Capellen. , the commune of Koerich has a population of 2,310. The other small communities in the commune are Goeblange, Goetzingen and Windhof. With its onion-towered church standing above the ruins of the medieval castle, Koerich has a particularly attractive rural setting although it is only 15 km west of Luxembourg City. Location The village lies in the valley of the Goeblange stream which flows down to the River Eisch to the west. It is at the junction of the CR 109 to Goeblange and Capellen and the CR 110 to Windhof and Dippach. The centre of the village is 295 m above sea level while the residential developments to the north and south rise to a height of 320 m. The streets in the village are therefore very hilly. The surrounding countryside is a mixture of forests and open fields with mixed farming. History The commune has a history extending back some 2,000 years. There is strong evidence that the Romans inhabited the area between the 1st and 4th centuries. To the south at Windhof the commune borders on the Kiem or Roman road from Trier to Reims and to the north-west, in the Miecher forest near Goeblange, impressive remains of a Roman farming community have been found. Two large villas have been excavated and the foundations partially rebuilt. There are other buildings and fortifications on the site which are now being uncovered. According to the commune's website, the first documentary reference to Koerich was in 979 but it was not until the 12th century that its two castles were built: the Fockeschlass of which all traces have disappeared though it is shown on the first cadastral map in 1771; and the Grevenschlass whose ruins still dominate the centre of the village. The castle 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. The watchtower, now 11 m tall, was certainly much higher when it was built. 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
