The Willibrord Chapel was allegedly founded by the missionary Willibrord. There was also a Willibrordus well near the chapel.
Although the current chapel dates from the 2nd half of the 19th century, the original chapel is said to be much older. This has been confirmed by excavations which took place in 1977. A cemetery was found, as well as the foundation of an older building, which was located under the current chapel. This building was built of boulders and boulders. Besides this building, the remains of a wooden construction were traced, which probably related to the eighth-century mission church. Later a Romanesque chapel was built, built of rubble stone and Maas boulders. The choir has been preserved.
Even after the St. Gertrude's Church was built in Gruitrode, a benefice remained attached to the chapel and Masses were occasionally celebrated by the parish priest. In 1715 there was a small, dilapidated chapel with a thatched roof. In the second half of the 19th century, the accessible chapel took on its present form: a modest brick building under a saddle roof, with a small roof turret.
