The Centre Pompidou-Metz is a museum of modern and contemporary arts located in Metz, capital of Lorraine, France. It is a branch of Pompidou arts centre of Paris, and features semi-permanent and temporary exhibitions from the large collection of the French National Museum of Modern Art, the largest European collection of 20th and 21st century arts. The museum is the largest temporary exhibition space outside Paris in France with 5,000 m2 (54,000 sq ft) divided between 3 galleries, a theatre, and an auditorium. The first piece of the monument designed by Japanese architect Shigeru Ban was laid on November 7, 2006, and the building was inaugurated by French President Nicolas Sarkozy on May 12, 2010. The building is remarkable for its roof structure, one of the largest and most complex built to date, which was inspired by a Chinese hat found in Paris by Shigeru Ban. Since its inauguration, the institution has become one of the most visited cultural venues in France outside Paris.
