Metz has a rich 3,000-year history,[8] having variously been a Celtic oppidum, an important Gallo-Roman city,[9] the Merovingian capital of Austrasia,[10] the birthplace of the Carolingian dynasty,[11] a cradle of the Gregorian chant,[12] and one of the oldest republics in Europe.[13] The city has been steeped in Romance culture, but has been strongly influenced by Germanic culture due to its location and history.[14]
