- © 1999-2015 by Lise Hull. A keep was a self-sufficient structure that castle defenders could retreat to as a last resort during a battle. The keep was originally called a donjon or great tower. In medieval documents the great tower is referred to as magna turris, and the word keep didn't come along in the English literature until the later half of the 16th century.

Almost all early keeps were square or rectangular, and were the easiest and fastest to erect.
