Any entrance through a wall, being an opening, forms an obvious weak point. To be practical, the entryway would have to accommodate supplies being brought through, yet difficult for attackers to breach. For example, passage over ditches or moats would have to be withdrawn to deny attackers. The use of multiple walls or ditches around an entrance would also make it difficult for defenders to use the entrance practically, necessitating better methods of control. Gates came in many forms, from the simple stone buttress and timber blocks,<ref name="Stoning and Fire at hill fort entrances of southern Britain">{{cite book|author=Avery, Michael|title=World Archeology|volume=18|date=October 1986|issue=2|pages=216–230}}</ref> to the massive and imposing stone archways and thick wooden doors most associated with medieval citadels.
