A door is a movable structure used to open and close an entrance, typically consisting of a panel that swings on hinges or that slides or spins inside a space.

When open, doors admit people, animals, ventilation, and light. The door is used to control the physical atmosphere within a space by enclosing the air drafts, so that interiors may be more effectively heated or cooled. Doors are significant in preventing the spread of fire. They act as a barrier to noise. Most doors are equipped with locking mechanisms to allow entrance to certain people and keep out others.

Doors are used to screen areas of a building for aesthetics, keeping formal and utility areas separate. Doors also have an aesthetic role in creating an impression of what lies beyond. Doors are often symbolically endowed with ritual purposes, and the guarding or receiving of the keys to a door, or being granted access to a door can have special significance. Similarly, doors and doorways frequently appear in metaphorical or allegorical situations, literature and the arts, often as a portent of change.

Famous quotes containing the word door:

    “... So it’s plain to be discerned
    That the shades of holy men
    Who have failed, being weak of will,
    Pass the Door of Birth again,
    And are plagued by crowds, until
    They’ve passion to escape.”
    William Butler Yeats (1865–1939)

    The one happiness is to shut one’s door upon a little room, with a table before one, and to create; to create life in that isolation from life.
    Eleonora Duse (1859–1924)

    It was so hard to pry this door open, and if I mess up I know the people behind me are going to have it that much harder. Because then there’s living proof. They can sit around and say, “See? It doesn’t work.” I don’t want to be their living proof.
    Gayle Gardner, U.S. sports reporter. As quoted in Sports Illustrated, p. 87 (June 17, 1991)
