Abbaye de la Paix Notre-Dame, Baroque abbey in Liège, Belgium.

Abbaye de la Paix Notre-Dame is a baroque abbey church at 52-54 boulevard d'Avroy in Liège, built of Meuse limestone. Its grey ashlar facade has an arched doorway with reddish-brown wooden doors, Ionic pilasters, two tall windows with greenish panes, and an upper level with a circular oculus, a niche holding a Virgin and Child, and a shaped gable topped by a stone cross. The design adapts the Gesù facade in Rome.

Benedictine nuns from Namur founded the abbey in 1627; a stone wall followed in 1642 and the cloister was finished in 1645. The church was begun in 1677 and completed in 1690 to plans by the nun Aldegonde Desmoulins of Mons, and the convent buildings were erected after her sudden death in 1692. Closed for 45 years after the French Revolution, the community returned and has remained since.

The church holds four altars: the main altar with statues of Saint Benedict and Saint Scholastica by Arnold du Hontoire (1690), and two side altars painted by Englebert Fisen showing the deaths of the two saints. Cornelis van der Veken carved a Saint Joseph with the Child and a guardian angel. The nuns' choir sits behind the east chapel, at right angles to the apse, so they could follow services unseen by the faithful.

The church stands at Boulevard d'Avroy 52-54 in the Avroy district, its entrance marked by the arched doorway with reddish-brown doors. The interior is split: the public nave opens around two side chapels and a flat-ended choir, while the nuns' choir sits behind the east chapel, perpendicular to the chevet, screened from view. Look for the 1737 Le Picard organ, listed as exceptional Walloon heritage in 1983.

The 1737 organ by Jean-Baptiste Le Picard is listed as exceptional heritage of Wallonia since 1983. The church's interior, with its Liège-Aachen furniture style, is also singled out as exceptionally preserved. The organ stands in a church whose nuns' choir was placed behind the east chapel, perpendicular to the apse, so they could follow services unseen.
