Metz is a city in northeast France located at the confluence of the Moselle and the Seille rivers. Metz is the prefecture of the Moselle department and the seat of the parliament of the Grand Est region. Located near the tripoint along the junction of France, Germany, and Luxembourg, the city forms a central place of the European Greater Region and the SaarLorLux euroregion.
Metz has a rich 3,000-year-history, having variously been a Celtic oppidum, an important Gallo-Roman city, the Merovingian capital of the Austrasia kingdom, the birthplace of the Carolingian dynasty, a cradle of the Gregorian chant, and one of the oldest republics in Europe. The city has been steeped in Romance culture, but has been strongly influenced by Germanic culture due to its location and history.
Because of its historical, cultural, and architectural background, Metz has been submitted on France's UNESCO World Heritage Tentative List. The city features noteworthy buildings such as the Gothic Saint-Stephen Cathedral with its largest expanse of stained-glass windows in the world, the Basilica of Saint-Pierre-aux-Nonnains being the oldest church in France, its Imperial Station Palace displaying the apartment of the German Kaiser, or its Opera House, the oldest one working in France. Metz is home to some world-class venues including the Arsenal Concert Hall and the Centre Pompidou-Metz museum.
