Arrow Loop

An arrow slit (often also referred to as an arrow loop or loop hole, and sometimes a balistraria) is a thin vertical aperture in a fortification through which an archer can launch arrows. The interior walls behind an arrow loop are often cut away at an oblique angle so that the archer has a wide field of view and field of fire. Arrow slits come in a remarkable variety. A common and recognizable form is the cross. The thin vertical aperture permits the archer large degrees of freedom to vary the elevation and direction of his bowshot but makes it difficult for attackers to harm the archer since there is only a small target to aim at.

Crenellated

A battlement (also called a crenellation) in defensive architecture such as that of city walls or castles, comprises a parapet (i.e. a short wall), in which portions have been cut out at intervals to allow the discharge of arrows or other missiles. These cut-out portions form crenels (also known as carnels, embrasures, loops or wheelers). The solid widths between the crenels are called merlons (also cops or kneelers). Battlements often have openings between the supporting corbels, through which stones or burning objects could be dropped on attackers; these are known as machicolations. A wall with battlements is said to be crenelated or embattled.

Portcullis

A portcullis (from the French "porte coulissante" or gliding door) is a latticed grille or gate made of wood, metal or a combination of the two. Portcullises fortified the entrances to many medieval castles, acting as a last line of defence during time of attack or siege. Each portcullis was mounted in vertical grooves in castle walls and could be raised or lowered quickly by means of chains or ropes attached to an internal winch.
