The castle then came into the hands of Gaspard de Heu who had married Velbrück's granddaughter. A partisan of the Dutch resistance and the House of Orange, de Heu was captured by the Spaniards, accused of heresy and treason, and publicly executed in Luxembourg's fish market in 1593. Philip II of Spain confiscated the property and entrusted it to Peter Ernst Graf von Mansfeld, the governor of Luxembourg. Through marriage, the castle became the property of Henri de Chalon and then Gaspard du Bost-Moulin who had to sell it after being ruined by the Thirty Years War. Acting on behalf of the Spanish king, Johann Baron von Beck, governor of Luxembourg, bought most of the property in 1639. He initiated the construction of the Renaissance castle in 1643 but after he died of injuries from the Battle of Lens in 1648, the work was completed by his son in 1649.
