Entrance

An entrance is a means of access into a building, room, or enclosed space, typically through an opening such as a door, gate, or portal. Entrance also refers to the act of entering a place. The term derives from the Old French entree, from enterer, meaning to go in; in English, it has long been used for both the opening itself and the action of entering.

In architecture, an entrance is the primary opening that marks the transition between exterior and interior. It may be a doorway, archway, gate, or portal and is often framed by features such as lintels, jambs, and a threshold. Many buildings include a vestibule or foyer to separate exterior conditions from interior space. Entrances can be monumental or discreet and may be recessed or projecting into the facade. Access can be via a single door, double doors, or a revolving door, with variations for weather protection and security.

Functional considerations include accessibility, egress, and weather sealing. Materials range from wood and metal to stone and glass. Modern entrances commonly incorporate automated doors, sensors, and security systems; include temperature and sound insulation; and comply with safety standards for emergency exits and handicapped access.

Culturally, entrances serve symbolic roles as thresholds, often framing first impressions in architecture and urban design. In theaters and venues, entrances or backstage access have practical and ceremonial importance. In literature and rhetoric, the word is used metaphorically to denote arrival, initiation, or introduction.

Beyond buildings, entrances occur in natural settings (cave mouths, gate-like rock formations) and in transport contexts (ship hatches, tunnel portals). As a verb, to entrance means to captivate or enchant, though this usage is unrelated to physical access.
