Gadlys, Llanilid has been described as a Timber Castle but is rejected as such.

There are earthwork remains.

This site is a scheduled monument protected by law.


An enclosure measuring 51.8m on the N, fronting a wet marshy area, 42.6m (W), 62.4m (S) and 50.2m (E). An internal scarp isolates the W third of the site connected with a now-vanished building. The entrance was just W of the SE angle. (Coflein)

Gadlys, listed under Medieval Moated Sites, is about 200 x 150ft. Much eroded, it has no known history. (Glamorgan-Gwent Archaeological Trust HER)

The monument comprises the remains of a well-preserved medieval moated homestead. This site may have been the administrative centre of the sublordship of Ruthin during the 13th century, possibly superseding the motte castle nearby (GM080). Its situation in low ground is a typical one for moated sites, and water could have been let into the moat from the boggy area to the north. All that remains of the site are low banks on the west, south and east sides of a roughly rectangular area. Slight vestiges of the moat which once surrounded it are visible on the west. (Scheduling Report)

Tentatively dated to 1245-1314. Spurgeon writes that Gadlys signifies military camp, castle bailey, or courtyard, and as late as 1951 the OS map designated it as a 'Roman Camp'. The site is probably the replacement to Llanilid castle but there is no evidence it was fortified.

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.
