Ynys Cefni, Llangefni has been described as a Timber Castle although is doubtful that it was such.

There are no visible remains.


Roughly circular site of limestone measuring approximately 80 yards by 100 yards and 10-15 ft in height. A saddle-quern and muller were discovered at this site in 1863. Possible motte site. (Coflein–J Hill 13/04/2004)

Ynys Cefni, 1 mile SSE of Llangefni Church - a possible occupation site. Roughly circular limestone outcrop about 80yds x 100yds and 10 to 15ft high, partly quarried away on the N and W. Only visible sign of occupation is a bank 2-3ft high along the NE base. In poor condition. A saddle quern and muller found here c.1863 during railway construction (RCAHMW). Mound shows on AP's. Site as described by RCAHM, the low scoop slope in the NE probably the result of drainage work in the area. Nothing known locally regarding the whereabouts of the finds, though there are several unprovenanced saddle querns in Bangor Museum. (Gwynedd Archaeological Trust HER)

Saddle-quern use did continue into the middle ages but it would seem most likely this was earlier. Possibly a Dark Ages precursor to the Tregarnedd moated site but seems very unlikely as a motte. Whatever was there before the railway will have been seriously damaged.

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.
