Manor houses in Judea (such as at Khirbet el-Muraq, Qasr e-Leja and Aroer) share the same basic layout—a square floorplan with a central courtyard and a fortified tower in one corner (highlighted in yellow) used for defense and storage as well as for symbolically expressing ownership of the land. Qumran (see plan below) conforms well to this model, according to Hirschfeld.
