The presence of a Roman fort beneath the Norman motte-and-bailey castle, itself under modern farm buildings at Colwyn Castle (Fforest Farm), Hundred House (SO 1075 5396), was first suggested by C.J. Spurgeon in 1974, and was confirmed the following year by excavation in the south-western bailey and again in 1982 by further observations, when 54 stanchion-holes were dug by machine for the uprights of a large new sheep-shed. The 1975 excavations examined deposits immediately to the rear of the north-west rampart (FIG. 1). Fragments of Roman pottery were associated with the primary deposits which overlay the gravelly clay subsoil.
