Clyn Pattel Mound has been described as a probable Timber Castle.

There are earthwork remains.

This site is a scheduled monument protected by law.


This mound, situated on the farm of Clun Pattel, is locally known as Green Castle, but it seems to possess no history, nor could any tradition relating to it be traced. The Tithe Schedule (No. 38) gives the name of the field within which the mound is placed as Castle Meadow; and this, together with the marked resemblance of the hillock to the usual military mounds of the county, dispels all doubts as to its original purpose. The mound has a base circumference of 360 feet. Its height is 15 feet; the diameter of the flat summit is 30 feet. Slight traces of a moat remain, but there are no signs of a bailey. The mound is within 50 yards of the parish church. (RCAHMW)

Earthworks thought to represent a medieval castle mount: a steep-sided sub-circular mound, some 32-34m across & 4.5m high, having a rather irregular summit area, some 17-20m across; there are traces of a ditch on the south & west, elsewhere the mound rises above the confluence of two minor watercourses: to the west a rectangular area, some 30m across, between the mound-ditch & a pond. (Coflein)

Motte and Bailey 0.7 - 0.9m high with flat top c 25m in diameter. Surrounded by a ditch in a stream bed on NW and SW, and a dry ditch on the W 3m wide and 20cm deep. Situated in a field used for pasture. (Scheduling Report)

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.
