Lellingen is considered one of the best-preserved traditional villages in the region. It has been designated a model village by the National Heritage Authority, preserving its authentic character to this day.
Lellingen, a charming village in the Oesling region, located about 10 kilometers east of Wiltz, is located at the intersection of three streams: the Lellgerbaach, the Pëntschbach, and the largest, the Clerve, which surrounds the chapel. The original chapel, dedicated to Saint Peter, was probably built around 1750 and consisted of an elongated building with four small windows. In the 19th century, the chapel was expanded and given its definitive form. With its unique architecture, the chapel features a narrow, elongated chancel and a higher, roof-shaped transept. In the center of the transept stands a small tower with a single bell dating from 1840, dedicated to Saint John. The interior is characterized by statues and reliquaries that reflect the rural piety of the Baroque and 19th centuries.
