The Impasse de l’Ange takes its name from the sign adorning the façade past which you enter. This narrow cul-de sac is made up of many small houses that strike a contrast with the imposing residences on Rue Hors-Château. On the gable of a house on the small square at the end of the cul-de-sac, there is a small wooden shrine dedicated to the Virgin Mary. These small alcoves are called potales in Liège and this one is a fine example of working-class piousness. In the narrow streets of the working-class districts of old Liège, there are still many of these potales.
