Latitude 53.31205° Longitude -3.41320°

Graig Fawr, Dyserth has been described as a Timber Castle although is doubtful that it was such, and also as a Masonry Castle although is doubtful that it was such.

There are uncertain remains.


Possible site of castle mentioned in 1241 as foundation of Henry III "near Rothelan". Visit 20.3.92 did not reveal the site (Latham, J 1992, 6). (Clwyd Powys Archaeological Trust HER 17813)

Series of banks on SE neck of Graig Fawr, probably combination of stock enclosures natural ridges and quarries. Seen by Beer as promontory fort, and Parry as the documented 1st Dyserth castle. Both unlikely.
Extensive area of irregular shaped banks of varying height, but no more than 2m. Some of the banks have been destroyed by late activity such as quarrying. (CCC, 1982)
Probable field system covering about 4 hectares. Banks with stone core and turf covering. Predate mining (Latham, J 1992,7). (Clwyd Powys Archaeological Trust HER 102191)

Said to be site of false start for castle, that mentioned in 1241 as founded by Henry III 'near Rothelan'. Graig Fawr is a complex archaeological site with much use in many periods including multiperiod metal ore mining presumably with associated spoil tips. This site is doubtful. Confusion is added by there being two listing in the HER for a castle site here one at SJ05958039 and another at SJ06188020.

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.
