Despite the city's small size, it has several notable museums: the recently renovated National Museum of History and Art (MNHA), the Luxembourg City History Museum, the new Grand Duke Jean Museum of Modern Art (Mudam) and National Museum of Natural History (NMHN). The city of Luxembourg itself is on the UNESCO World Heritage List, on account of the historical importance of its fortifications. In addition to its two main theatres, the Grand Théâtre de Luxembourg and the Théâtre des Capucins, there is a new concert hall, the Philharmonie, as well as a conservatory with a large auditorium. Art galleries include the Villa Vauban, the Casino Luxembourg and Am Tunnel.
