A museum is a building or institution which houses a collection of artifacts.
Museums collect and care for objects of scientific, artistic, or historical importance and make them available for public viewing through exhibits that may be permanent or temporary.
An Art museum, also known as an art gallery, is a space for the exhibition of art, usually in the form of art objects from the visual arts, primarily paintings, illustrations, and sculpture. Collections of drawings and old master prints are often not displayed on the walls, but kept in a print room. There may be collections of applied art, including ceramics, metalwork, furniture, artist's books and other types of object. Video art is often screened.
History museums cover the knowledge of history and its relevance to the present and future. Some cover specialized curatorial aspects of history or a particular locality; others are more general. Such museums contain a wide range of objects, including documents, artifacts of all kinds, art, archaeological objects. Antiquities museums specialize in more archaeological findings.
Maritime museums specialize in the display of objects relating to ships and travel on seas and lakes. They may include a historic ship (or a replica) made accessible as a museum ship.
Science museums and technology centers revolve around scientific achievements, and marvels and their history.
Archaeology museums specialize in the display of archaeological artifacts. Many are in the open air, such as the Acropolis of Athens and the Roman Forum. Others display artifacts found in archaeological sites inside buildings.
