Margaret of Valois
In 1577, when Margaret of Valois was travelling to Spa, Groesbeeck lent her his palace, himself temporarily moving to the Abbey of Saint-Jacques. The royal visit was the occasion for a series of celebrations, banquets and exchanges of gifts. She described her host as "a lord accompanied by much virtue, prudence and goodness, who speaks French well; agreeable of person, honourable, magnificent and agreeable company."
