Aberllynfi Castle is a compact motte and bailey occupying a diamond-shaped area on a natural bluff roughly 80m by 78m. The motte is at the western end. It is 30-35m in diameter at the base, up to 6.0m high, the summit being 16-17m across. (Coflein)

The monument comprises the remains of a motte and bailey castle, a military stronghold built during the medieval period. The site is keyhole shaped in plan and located on the end of a small bluff which is surrounded on three sides by water meadows bordering the Afon Llynfi. The motte has a base diameter of 34m, is 6m high and has a flat summit 16m in diameter. The bailey lies to the E of the motte and measures 50m by 30m. It is separated from the motte by a the filled-in remains of a ditch, and is bounded by natural slopes to the N and S. An original causewayed entrance crosses the moat on the S side.

Gatehouse Comments

Site recorded as captured in 1233. Hogg and King writes that although survived well into C13 never rebuilt in stone, Remfry writes stone lying about near motte may suggest stone round tower. Sometimes identified with the vanished Glasbury Castle although Kings is certain this was a different castle (see Glasbury).
