An art museum or art gallery is a building or space for the display of art, usually from the museum's own collection. It might be in public or private ownership, be accessible to all, or have restrictions in place. Although primarily concerned with visual art, art museums are often used as a venue for other cultural exchanges and artistic activities, such as lectures, jewelry, performance arts, music concerts, or poetry readings. Art museums also frequently host themed temporary exhibitions, which often include items on loan from other collections.
