Hilston Park is a country house and estate between the villages of Newcastle and Skenfrith in Monmouthshire, Wales, close to the border with Herefordshire, England. The house and park are in the Monnow valley, beside the B4347 road, by road northwest of Monmouth and just over southwest of Skenfrith.
The Palladian mansion, built in 1838 for Bristolian banker George Cave, is a Grade II* listed building, the grounds and landscape park are registered on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales and the park's flower meadow is a Site of Special Scientific Interest. The park includes an early 20th century lodge at each of the two entrance gates; a ruined coach house; a lake, boathouse, and pond; several streams, gardens, and wooded areas; and Hilston Tower, a late 18th-century folly of red sandstone in the grounds's northeastern corner.
The house served as a residential outdoor education centre, operated by Gwent Outdoor Centres and supported by the local authorities of Newport, Torfaen, Blaenau Gwent and Monmouthshire until 2019. In 2020, the councils decided to consolidate their outdoor education facilities on a single site, and Hilston Park was deemed surplus to requirements. The house was sold at auction in 2021.
History
Hilston House was for many years the principal estate and mansion in the parish of St. Maughans. In the 17th and 18th centuries it was the residence of the Needham family, although Henry Milbourne, an important 17th century magistrate of the county, is also reported to have lived here at one time. Sebastian Needham is said to have been buried at Skenfrith, on 26 March 1723, having fathered nine children. The house remained in the family, who were Catholic, for four generations. Following this stable period of ownership, accounting for about a century, the estate then changed hands a considerable number of times within the next 70 years. It was eventually sold by John Needham, a barrister of Gray's Inn, to Sir William Pilkington when Needham moved to Somerset. Pilkington sold it to James Jones of the Graig, who sold it to Sir Robert Brownrigg, G.C.B. a distinguished officer in the Peninsular War. He died on 27 May 1833, aged 76 years and his monument may be seen on the south wall of St. Maughan's Church. After his death the house was sold to Thomas Coates of Lancashire. Shortly afterwards, on 12 September 1838, the house was destroyed by fire.
It was then sold to George Cave, a banker of Bristol, who was responsible for building a new Palladian mansion which remains today. He sold it to Alfred Crawshay, who sold it to John Hamilton who finally completed the building. His son, Captain Pryce Hamilton, brother to Alice Mary Sinclair, seems to have added considerably to the Hilston Estate and it appears that he also purchased Norton Court, Skenfrith from Henry Somerset, 8th Duke of Beaufort, and bought Skenfrith Mill and Lower Dyffryn House, Grosmont around 1870.
Pryce Hamilton sold Hilston House in about 1873 to James Graham, High Sheriff of Monmouthshire in 1881, who passed the house on to Douglas William Graham, who was living at Hilston in 1902, when the hall was panelled with the oak from the hall of the Lower Duffryn. Graham was also responsible for other improvements, the stone and brick buildings at Home Farm, the Lodges, New Cottages and the reservoir. It was then owned for some time by the Lawley family, who had made their fortune in shipping and cotton in Manchester. In the 1930s, Hilston Park was the residence of Edmund Henry Bevan (High Sheriff of Northamptonshire in 1912), whose riches were by inheritance from the Portland cement made at Bevan Works in Northfleet, Kent. He married Joan Mary Conyers Norton, the eldest daughter of the 5th Baron Grantley, in the 1930s.
It was purchased by T. E. Davies in the 1940s, who sold the house and estate on 17 October 1947. In the 1950s, the house was converted to a school. It became an outdoor education centre in 1971. It continued as a residential centre, operated since 1996 by Gwent Outdoor Education Service, a joint service supported by the four local authorities of Blaenau Gwent, Monmouthshire, Newport and Torfaen until 2019. In 2020, cost pressures led the councils to decide to consolidate their outward bound activities at a single site near Cwmbran, and Hilston Park was deemed surplus to requirements. It was sold at auction in March 2021.
