The 16th-century parish church on the central square, plain on the outside but housing the Egmont crypt — the burial place of Lamoral van Egmont and several generations of his descendants. The crypt can be visited during church opening hours.
The interior of the church is a mix of late-Gothic and Baroque, with several memorial slabs to Egmont family members and a small treasury of religious silver. Free entry; modest dress requested during services.
