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.

This is likely to be the 'Twyn y Klommendy' ('Dovecote Hill') 'suppos'd to be an old Krig', noted in Lluyd's Parochialia (1910 edition, 30). It is possible that the castle mound was co-opted as a viewing platform in association with the nearby Great House.
