Wirich Ist, Lord of Koerich, Seneschal of the court of Luxembourg, started building the castle in the late 12th and early 13th Century. The tower - known as 'witches tower' - and the exterior walls are of late romanesque style. It has a 12 x 11.6 m base and a thickness of 3 to 3.5 meters, and -though currently only 11 metres high- its estimated original height of 25 to 30 metres made this one of the most imposing towers in our region.
