In 1189 Richard Cotele, one of Glastonbury abbey's most prominent tenants, did homage for a castellarium in the manor of Brent Marsh. Elias Cotele, son of Richard, granted it with his mother's consent to Robert, son of Thomas de la Pulle. From Thomas it passed to Reginald de Mere and Reginald gave it in 1270 to Abbot Robert of Petherton. The name Brent Marsh implies a site on the low-lying land east or south of Brent Knoll; no such site has yet been found. (Dunning 1995)

There is an iron age hillfort on the very prominent Brent Knoll (at the given map reference); did this have medieval use? Is the castellarium mentioned an actual medieval castle (in the sense of a manorial centre), the iron age hill fort (with or without medieval residential occupation - although the hill top can never have been a easy place for a residence - even in the Iron Age - and certainly not for medieval people and their horses), or lands associated with something else? Did the dry lands of Brent Knoll have particular value in the otherwise marshy area? The lower slopes of the hill have a concentration of settlement and possibly a manor house on these lower slopes may have been modestly fortified.
Dunning is of the opinion that medieval use of the term castellarium is not associated with unoccupied Iron Age hillforts however Gatehouse does not share that opinion.

Minor archaeological investigations, such as watching brief reports, and some other 'grey' literature is most likely to be held by H.E.R.s but is often poorly referenced and is unlikely to be recorded here, or elsewhere, but some suggestions can be found here.
The possible site or monument is represented on maps as a point location. This is a guide only. It should be noted that OS grid references defines an area, not a point location. In practice this means the actual center of the site or monument may often, but not always, be to the North East of the point shown. Locations derived from OS grid references and from latitude longitiude may differ by a small distance.
