The parish of Mamer was first mentioned in a document in 983. The small thatched chapel was enlarged over the centuries, in line with the needs and growth of the population. In 1720, a single nave was added to the 16th-century choir, and between 1723 and 1738 it was fitted with Baroque furniture by the famous firm Greeff d'Altwies. Following restoration work on the church and the Greeff furniture between 1993 and 2003, experts consider it to be a jewel of clarity and colour.

With the idyllic valley of the River Mamer as its backdrop, this footpath will lead you to a wide variety of places, from the remains of the Roman spa in Mamer to the Tour St Michel in Mersch, via several old mills and the impressive tower of Schoenfels Castle.
