 Martin's "cultus" survived the passage of power to the Merovingians' successors, the Carolingian dynasty.In 1860 excavations by Leo Dupont (1797–1876) established the dimensions of the former abbey and recovered some fragments of architecture.The tomb of St. Martin was rediscovered on December 14, 1860, which aided in the nineteenth-century revival of the popular devotion to St. Martin.
