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:

    In my experience, if you have to keep the lavatory door shut by extending your left leg, it’s modern architecture.
    Nancy Banks-Smith, British columnist. Guardian (London, February 20, 1979)

    Wistfully watching, with wonderful liquid eyes.
    And all her weight, all her blood, dripping sack-wise down towards
    the earth’s center,
    And the live little-one taking in its paw at the door of her belly.
    —D.H. (David Herbert)

    We are well advised to keep on nodding terms with the people we used to be, whether we find them attractive company or not. Otherwise they turn up unannounced and surprise us, come hammering on the mind’s door at 4am of a bad night and demand to know who deserted them, who betrayed them, who is going to make amends. We forget all too soon the things we thought we could never forget.
    Joan Didion (b. 1934)
