The House of Beaufort became ruined by the Thirty Year War and thus was forced to sell up. On 27.11.1639 Johann Baron von Beck, governor of the province of Luxembourg on behalf of the Spanish King, acquired the greatest part of its properties. It is likely that he built the wing with the large Renaissance style windows in the main tower and the northwestern cannon tower. After 1643 he ordered the building of the new renaissance chateau. Johann von Beck, however, died of injuries received at the Battle of Lens in 1648 before he could even move in. His son finished the construction in 1649.
