Castell Pen yr Allt has been described as a certain Timber Castle, and also as a certain Masonry Castle.

There are masonry footings remains.

This site is a scheduled monument protected by law.


Earthworks thought to represent the remains of a medieval castle. These include a banked and ditched, generally polygonal enclosure, about 52m north-west to south-east by 50m, tapering to about 30m on the north-west. It rests on steep natural slopes on the south-east, with its ditches springing from natural declivities. Where the enclosure faces rising ground, to the north-west, the ramparts are now greatly degraded but are thought to have been doubled, whilst on the south-east the ditch is represented by a ledge above the natural slopes. Set rather off centre in the southern part of the enclosure is a ditchless steep-sided sub-circular mound, some 16-20m across & 2.4m high, having a summit area about 9.0m in diameter. It is possible that this mound represents the remains of a freestanding circular masonry tower. (Coflein)

A fine and well-preserved mount-and-bailey earthwork standing 300 yards north-east of the parish church. The motte has a height of some 8 feet, and a summit diameter of 30 feet. The bailey, a circular plateau of 8 feet in height, is placed to the north of the mound; it is surrounded by a rampart and formidable ditch, averaging 30 feet from the crest to the floor. The ditch is 10 feet wide; it was scarped and counterscarped. To the south the ground falls steeply to a strong spring of water. In 1864 it was stated by a neighbouring vicar that he remembered remains of an old stone tower about 30 feet in diameter on the top of the mound. At present the summit displays no signs of buildings. (RCAHMW)

Although described as a motte and bailey by the RCAHMW and some others this is a ringwork with a collapsed, probably round, tower.

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.
