Saint Stephen's Church in Strasbourg is located inside the catholic ‘Saint-Étienne’ college in Strasbourg, for which it serves as a chapel.
Saint Stephen's is one of the oldest churches in Strasbourg. The crypt contains the remains of a fifth-century Roman basilica. The site was originally occupied by a Roman fort.
A new church was built on the site in early in 717 by Duke Adalbert of Alsace, brother of Saint Odile, as part of a new convent, in which he installed his daughter Attala as the first abbess.
