There is some disagreement in the literature about the foundation of the Deuster chapel. According to some, the chapel was founded in 1660. After all, that date was chiselled into a wall. However, this stone was not found and was probably lost during the later renovation. According to others, the chapel was founded in 1687 by Petrus Moors (1660-1703). Moors cherished a great devotion to Mary and, according to tradition, placed a statue of Our Lady that hung in a lime tree in a chapel. In 1717, the chapel was expanded to the west, possibly by Jan Moors (1647-1720), Petrus' older brother. From 1700 to 1820, a hermit lived in a hermitage that was attached to the chapel. He was responsible for the maintenance of the chapel, assisted the priests when they came to say Mass there, and taught the children. In 1735 the chapel came to the parish of Peer. In 1799 the roof turret and the cross were removed by the French, and the chapel was put out of use. Around 1860 the vault was demolished. In 1970 the majority of the interior was transferred to the Sint-Trudokerk in Peer. In 1982 the chapel was restored. Traditionally the small livestock market took place around the chapel, most recently in 1991.
