Cas Troggy Castle has been described as a certain Masonry Castle.

There are masonry ruins/remnants remains.

This site is a scheduled monument protected by law.


The tower at 'Cas Torrogy' is recorded as being newly built in 1307. The surviving remains consist of a rectangular platform, c.42m north to south by 27m, set on low ground close by a stream on the north. It is defined by ruinous walls and a moat, c.15m wide on the west and 10m across on the north. On the south front two towers, of indeterminate form, project to extend the frontage to 64m. (Coflein)

Hidden among the bushes and trees are the remains of a castle built by Roger Bigod III, earl of Norfolk, as a hunting lodge. It is mentioned in 1305, as a newly built tower was probably left incomplete at his death in 1306. A rectangular court was surrounded by walls said to be of poor masonry, perhaps a reflection of the earl's financial difficulties. The surviving south wall (right), however, is well built. The fireplace and two window embrasures in it at the upper level, and probably served the main hall. At each southern corner are remains of towers with octagonal interiors up to 6m in diameter. The outer faces are too damaged for the external shapes to be made out. The SW tower has traces of a staircase and the SE tower has a big cess-pit beside the stub of the east curtain and a rectangular projection is set alongside the south curtain. (Salter, 1991)

Called Striguil or Struggle in error by some writers, this name belongs in fact to Chepstow.

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.
