Clovis I and his successors of the Merovingian dynasty built a host of religious edifices in Paris: a basilica on the Montagne Sainte-Geneviève, near the site of the ancient Roman Forum; the cathedral of Saint-Étienne, where Notre Dame now stands; and several important monasteries, including one in the fields of the Left Bank that later became the Abbey of Saint-Germain-des-Prés. They also built the Basilica of Saint-Denis, which became the necropolis of the kings of France. None of the Merovingian buildings survived, but there are four marble Merovingian columns in the church of Saint-Pierre de Montmartre.[31] The kings of the Merovingian dynasty were buried in the Abbey of Saint-Germain-des Prés, however Dagobert I, the last king of the Merovingian dynasty, who died in 639, was the first Frankish king to be buried in the Basilica of Saint-Denis.
