Хильдеберт I
It occupied part of the current site of boulevard Saint-Germain in the SE corner of the enclosure of the Abbey of Saint-Germain-des-Prés. The abbey dated to the earliest era of Paris, when Childebert I (on the site of a temple to Isis or Ceres, according to legend) founded a monastery dedicated to the Holy Cross and to St Vincent of Saragossa, which later took the name of its administering bishop Germain of Paris. Its basilica became known as "Saint-Denis of the Merovingians", since it contained the tombs of Childebert I and others of the dynasty.
