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 alliegiance 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, 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.


Farmhouse, later C16 crosswing with early C17 lower range at right angles running N. Whitewashed rubble stone with slate roofs and brick stacks, T plan. Lower range is single storey with attic dormers, catslide roof to rear. Larger crosswing is of 2 storeys with end stacks and has projecting latrine chute to E gable end. Lower range E front has red brick ridge stack right of centre, 2 stone dormers to left, casement pairs with timber lintels, over C17 Tudor-arched door in rectangular oak frame and cambered-headed casement pair. A blocked light further right, in line with chimney and a casement pair to extreme right with timber lintel. N gable end has 3-light timber diamond-mullion windows to loft.
Crosswing has ground floor casement pair and first floor triple casement under eaves in N return. E gable end is windowless but for tiny stair-light to centre right and smaller light above in attic. To left is projecting slate-roofed latrine.
S front is altered in C19 and C20. Three casement pairs above under eaves, and tiny stair light under eaves to right. Ground floor has large triple casement to left with timber linteland 9-pane window joined to 6-6-pane casement pair under single timber lintel with brick pier between. C20 stone-tile sills.
