Maps of the Cogan area before the 1850s invariably mark the Cogan Pill and Cogan Pill House, but it is unclear when this house (now known as The Baron's Court) was first built. The historian David King suggested the site as a possible location for an earlier castle, but any early fortifications have yet to be identified. A House was certainly extant by the 1290s when a weir, ("La Niwere", New wier) is recorded as forming the boundary of "Cogan Moor", and a fishery is recorded as belonging to "The Lordship of Cogan" by 1492 at a place called "Neke" (The Neck/Nook).
