Stow Hill Motte has been described as a certain Timber Castle.

There are no visible remains.


Motte, supposedly of 1100 buried in tunnel spoil in the 1840's. 'it was a circular mound with a flat top some 50 feet in diameter and surrounded by a ditch' (Banks quoted in Phillips)

Twyn Gwynlliw stood very near the church of St. Wollos; the extension of the town of Newport in that direction has, I believe, occasioned its removal. (Wakeman)

According to tradition, Newport developed following St. Gwynllyw’s foundation of a church at the top of Stow Hill in the late fifth or early sixth century, though there is no evidence to support this claim. It appears that there was a Welsh settlement, with some Saxon influences, on the site by the tenth century, and following the Norman Conquest of England Robert de Hay is believed to be responsible for the construction of the motte on Stow Hill around which the town grew at the lowest point on the River Usk. Newport Castle was completed in the mid- to late-fourteenth century, and a town charter of 1427 confirmed its status as a market town which controlled the river crossing. (Coflein)

Probably the original castle of Newport. Wakeman's comment "very near" suggests the given map reference may be inaccurate. St Wollos is now Newport Cathedral and is at ST308875 some 400m from the map reference given in the Glamorgan-Gwent Archaeological Trust HER. A location nearer the church (adjancent or with 100m) would be more usual.

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.
