An art museum or art gallery is a building or space for the exhibition of art, usually visual art. Museums can be public or private, but what distinguishes a museum is the ownership of a collection. Paintings are the most commonly displayed art objects; however, sculptures, decorative arts, furniture, textiles, costumes, drawings, pastels, watercolors, collages, prints, artist's books, photographs, and installation art are also regularly shown. Although primarily concerned with providing a space to show works of visual art, art galleries are sometimes used to host other artistic activities, such as performance arts, music concerts, or poetry readings.
The term is used for both public galleries, which are non-profit or publicly owned museums that display selected collections of art. On the other hand, private galleries refers to the commercial enterprises for the sale of art. However, both types of gallery may host traveling exhibits or temporary exhibitions including art borrowed from elsewhere.
In broad terms, in North American usage, the word gallery alone often implies a private gallery, while a public gallery is more likely to be described as an art museum. In British and Commonwealth usage, the word gallery alone implies a public gallery, while a private or commercial gallery will be distinguished using those terms, and the word museum alone is generally understood to refer to institutions holding collections of historic, archaeological or scientific artefacts, rather than of fine art.
