 Whatever its name, a typical gate consists of two hinged doors.Often they will be only half-height, but sometimes they go almost all the way to the top of the opening.The doors themselves are made of wood or metal and usually have painted on them an icon of the Annunciation in the form of a diptych (the Theotokos on the right door, and the Archangel Gabriel on the left), either alone or with the four Evangelists.
