Buenos Aires has a thriving arts culture, with "a huge inventory of museums, ranging from obscure to world-class." The ''barrios'' of Palermo and Recoleta are the city's traditional bastions in the diffusion of art, although in recent years there has been a tendency of appearance of exhibition venues in other districts such as Puerto Madero or La Boca; renowned venues include MALBA, the National Museum of Fine Arts, Fundación Proa, Faena Arts Center, and the Usina del Arte. Other popular institutions are the Buenos Aires Museum of Modern Art, the Quinquela Martín Museum, the Evita Museum, the Fernández Blanco Museum, the José Hernández Museum, and the Palais de Glace, among others. A traditional event that occurs once a year is ''La Noche de los Museos'' ("Night of the Museums"), when the city's museums, universities, and artistic spaces open their doors for free until early morning; it usually takes place in November.
