Diest: Introduction

Sat, 16 May 2026 00:00:00 GMT

In the small parish church of St. Sulpitius in Diest lies the tomb of Philip William, Prince of Orange - eldest son of William the Silent, the man who led the Dutch Revolt against Spain. The detail that twists the dynastic story is this: Philip William, alone among his siblings, remained a devout Catholic all his life. While the rest of the family carried the Protestant cause that would eventually produce the Kingdom of the Netherlands, Philip William asked in his will that this small Catholic church in this small Belgian town celebrate a yearly Requiem Mass for his soul. The town of Diest, controlled by the House of Nassau between 1499 and 1795, was the family's southernmost holding - and the one place where the Orange name still meant something Catholic, even as the rest of the family climbed Protestant thrones to the north.
