Gate

From Wikipedia, the free encyclopedia

This article is about the point of entry or exit. For other uses, see Gate (disambiguation).

Gates to official residences often feature elaborate ironwork.

A gate is a point of entry to a space enclosed by walls, or an opening in a fence. Gates may prevent or control entry or exit, or they may be merely decorative. Other terms for gate include yett and port.

Larger gates can be used for a whole building, such as a castle or fortified town, or the actual doors that block entry through the gatehouse. Today many gate doors are opened by an automated gate operator.
