This chapel in Aldeneik is dedicated to Harlindis and Relindis, the two daughters of Adalardus, a Frankish nobleman and founder of the Aldeneik monastery.
Both have been abbesses of this monastery. A Willibrordus well is built against the choir. This is a possible baptismal font from the time of the foundation of the monastery (around 780), the inside of which is covered with mesh boulders.
