History

Small country house, in late Georgian style with some Gothic detail, built in 1831 by the Tredegar estate for the Rev. C.A.S. Morgan, died 1875, vicar of the parish, younger brother of the 1st Lord Tredegar, sometime Chancellor of the Diocese of Llandaff and chaplain to Queen Victoria. The W end section with full height canted bay may be a slightly later addition. Two parallel ranges, originally three, but, after sale by the Tredegar estate in the mid C20, a parallel rear service wing was removed such that the entrance side which had 3 gables now has 2. The architect for this work and the restoration of the remainder was W.S. Thomas of Newport. The house was rented just prior to sale by Peter Thorneycroft, MP for Monmouth and later chairman of the Conservative party.
The special interest of the house is in the Georgian Gothic entrance hall with its extraordinary winding stair, and also its picturesque garden setting with romantic Gothic features: bee-bole, range of outbuildings (The Bothy), miniature lake with humped bridge, winding paths, and castellated corner features to the estate walls.
