History

C16 and C17 gentry house, now farmhouse. Sited on an outwork of a Norman motte and bailey castle (Scheduled Ancient Monument MM 098) which suggests a long history of habitation. In the 17th century the house was lived in by the Aylworth family. Bradney speculates that this family may have included, under the alias of William Aylesworth (b.1625 Monmouthshire), William Harcourt, one of the Catholics involved in the Titus Oates plot. Certainly, the Aylworth's were recusant Catholics during the C17, John Aylworth refused to take the oath of allegiance to George I. His son, John (d.1726) left the estate to a nephew John Gosling, a cooper of Chepstow. By the C19 part of the Beaufort estate, was sold by the 9th Duke c1900 to the current owners Monmouthshire County Council.
Fox and Raglan suggested that the crosswing was the solar range of a demolished hall replaced by the lower range added on as a kitchen range. The highly ornate timber mouldings place the house in the small group of houses, including Coldbrook and the Old House in this area, of unusually rich carpentry, dated to late C16. The stair at both ends indicates a solar over the parlour, not accessible from the other first floor room.
