One unusual feature is the large number in the Witham Valley In this article alien houses are included, as are smaller establishments such as cells and notable monastic granges (particularly those with resident monks), and also camerae of the military orders of monks (Templars and Hospitallers). The numerous monastic hospitals per se are not included here unless at some time the foundation had, or was purported to have the status or function of an abbey, priory, friary or preceptory/commandery.
