Page "Metz" Paragraph 10

Since King Sigibert I, Metz was frequently the residence of the Merovingian kings of Austrasia.

When the Carolingians acceded to the Frankish throne, the town preserved the good-will of the rulers as it had long been a base of their family and their primal ancestors ; Saint Arnuff and Chlodulf had been bishops of Metz.

So, Emperor Charlemagne considered making Metz his imperial capital, before he finally decided in favor of Aachen.

His sons, King Louis the Pious and Bishop Drogo of Metz, were buried in the Basilica of Saint-Pierre-aux-Nonnains in 840 and 855, respectively.
