Walferdange Castle (Luxembourgish: Walfer Schlass; French: Château de Walferdange), located in the small town of Walferdange in central Luxembourg, dates from 1824, when William I of the Netherlands, who was also Grand Duke of Luxembourg, built it as a stud farm. It was a part of the University of Luxembourg[1] and since 2015 has been used by the Ministry of National Education, Childhood and Youth (Luxembourg).
