The Quirinuskapelle is a chapel in Luxembourg City. It is located in the Petrusse valley, right next to a rock spring that was said to have healing properties. In all probability, the rock spring was also the reason why there had already been a pagan place of worship in the same place, which was converted into a Christian sanctuary in late Roman times. In the 11th century the chapel was consecrated to the Christian martyr Quirinus von Neuss.

The chapel in its current form includes a part carved into the rock and a Gothic porch, the facade of which was built by the Teutonic Order in 1355. The roof and the small bell tower are from the 19th century. In 1900, a scientific investigation of the spring was carried out, which revealed that the spring water had no medicinal effects according to the state of the art at the time.
