Llyn Gwyn Enclosure has been described as a Timber Castle although is doubtful that it was such.

There are earthwork remains.

This site is a scheduled monument protected by law.

Description

A semicirclar run of bank and ditch defines an enclosure, c.50m by 24m, otherwise resting on a relict lake-bank scarp to the SW. (Coflein as ?Iron Age defended enclosure)

Crescentic bank and outer V-shaped ditch. Open end abutting old NE bank of lake. About 80m by 30m. Probably defensive site (Ditch possible originally water filled). Traditional association with Strata Florida Abbey. (Clwyd Powys Archaeological Trust HER as medieval defended enclosure)

The Llyn Gwyn Earthwork consists of a crescent-shaped bank with an outer V-shaped ditch, enclosing an area of c.50m by c.24m. The scarp along the otherwise open south-west side probably represents the original bank of the lake, which is somewhat smaller today, and the ditch may have been water-filled. The remains are not especially diagnostic as to date, though they are traditionally associated with Strata Florida Abbey. (Scheduling Report - Site Type - Earthwork (unclassified): Period - Unknown)

Comments

The Castles of Wales web site has a database which states, under the name Treflyn (aka Llyn Gwyn) at SO012650, 'small motte visible' but gives no authority. Nothing in the official descriptions or on the air photo suggests a motte here. The original form of the earthwork appears to have been a oval ring-bank half of which has been eroded away, presumably at a time when the lake was somewhat larger. The actual nature and function of the site is obscure but a medieval residence of a water bailiff may be a vague possibility.

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.
