By 1250, a parish with a church building already existed. In the Middle Ages, an imposing castle was built, inhabited by the Lords of Pietersheim and later by the Counts Van den Bergh. The castle had its own chapel.
In 1702, the fortress, built by the Spanish in 1633, passed into state ownership. A garrison of predominantly Protestant soldiers was stationed there. They used the castle chapel for services. The altar was moved outside, and the pulpit was given a prominent place in the building. The first vicar, Jacobus Hensbroek, took office on October 7, 1702.
Count van Hompesch, who had resided at Walborgh Castle since 1719, was a Protestant. He protected the Protestant community, and thus it was maintained amidst a strong Catholic environment. During the French period, the building was used for other purposes. After the French withdrew, the building could no longer be used as a church and fell into disrepair.
The congregation asked King William I for help, who provided 1,100 guilders, which was used to build a new church in 1819. The castle's residents also contributed. For example, Countess Charlotte van Hompesch donated a special organ to the church. A beautiful set of oak choir stalls bearing the family crests was also installed.
