The charming little village of Grumelange is nestled in the valley bottom, in a loop of the Sûre which acts as the border between Belgium and the Grand Duchy of Luxembourg. It includes a group of beautiful traditional farms built in the 18th century and subsequently modified. In the centre of the village stands a small religious building that looks like a church but which bears the title of chapel. This name is explained by the fact that it was never the seat of a parish. This beautiful rendered and whitewashed building was built on the initiative of the Kuborn brothers, two priests from the area. On the south side, there is a tower incorporated into the slate roof on a wooden cornice. It is pierced by a semi-circular entrance gate engraved with the year 1700 which tells us about the date of its construction. At the top, a bell tower is topped with an octagonal slate spire studded with a cross and a wrought iron rooster. The two-bay nave is lit by semicircular bays framed in Lorraine limestone, locally nicknamed Pierre de France. The sanctuary ends with a three-sided chevet. Since 2000, it has housed a remarkable schist altar. The whole building underwent a complete and exemplary restoration in 2015.
Classified as a monument and established a protection zone on 9 December 1991.
