Historical Information

Described by Brett as, ‘by far the largest and grandest house in north County Down’, Hillsborough Castle was for one hundred and fifty years the home of the Marquesses of Downshire and has lately provided accommodation for royalty, ministers and high-level dignitaries from home and abroad, as well as being a venue for less formal occasions, such as charitable events. (Brett, p.90, Hillsborough Castle, p.5) Hillsborough is named after the Hill family who came to Ireland from the west country in the late sixteenth century. Moses Hill obtained extensive estates through conquest of Irish chieftains and built a fortified house at Hill Hall in the early 1600s. His younger son Arthur Hill was the first to live at Hillsborough and reconstructed Hillsborough Fort which had been destroyed in the 1641 rebellion. The village of Hillsborough was given borough status after the restoration in 1660 and had a corporation and the right to elect two MPs to the Irish government. The town thenceforth became the residence of the Hill family, who increased in prominence and prosperity, Trevor Hill becoming Baron Hill and Viscount Hillsborough in 1717. In the late seventeenth century Trevor Hill built a house close to the terrace of the present Castle. No drawings or plans survive but Harris described it as ‘a noble large house built within the area of a regular fortification.” This house was burnt down in an accidental fire, sometime in the late 1730s. (Hillsborough Castle, p.10-12) Wills Hill, the first Marquess of Downshire (1718-93), built a mansion house to the south east of the present house, in Large Park, the remains of which are still present. It is clear from Mrs Delaney’s observations of 1758 that Lord Hillsborough had in mind the construction of a new mansion at that time, but an estate map of 1771 shows only a schematic representation of a terrace of houses on the western side of the square. The Archaeological Survey of County Down asserts that a house was built on the site soon after 1758 but appears to be basing this assumption on a map of uncertain date which could not be located. Establishing a date of construction is hampered by the fact that ‘Hillsborough Fort’ as it is now called was also known as ‘Hillsborough Castle’ at this time. However, the present house is shown unequivocally on an estate map ‘surveyed 1788’ by W Byers. The house consists of two large rectangular wings orientated north to south with a narrow internal courtyard. A pathway from the Square leads through the house from east to west. Brettingham’s drawings dated by PRONI to c.1788, depict the west front as presently constructed and in an annotation to another drawing, Brettingham describes himself as ‘the architect of the west range of the house itself’. However, Brettingham’s involvement with the design of the remainder of the house at this stage is not clear. (Mrs Delaney, quoted in Archaeological Survey of Down, p.409, Archeological Survey of Down, p.414) The construction of his own house was only part of Hill’s plans, his scheme also included the building of a new town with a market house at the centre and the rebuilding of the Fort and the parish church. Wills Hill was the Secretary of State for the Colonies during the independence struggle and Hillsborough was visited by Benjamin Franklin in October 1771 and this was reported in communciation dated January 1772. Unfortunately Franklin and Hill disliked each other, Hill being unable to countenance American independence. King George III later blamed the Marquess for the loss of America. (Hillsborough Castle, p.20, Walker, p.9, www.oxforddnb.com) The second Marquess, Arthur Hill (1753-1801), was able to make additions and alterations to the house due to the wealth of his heiress wife and again engaged Brettingham who added a library to the south-east of the original house and then a thirteen-bay south front c.1795. Numerous drawings have survived, showing Brettingham’s designs for the house both internally and externally, some of which were clearly carried out and others which may have been more speculative. A series of letters from William Forsyth, clerk of works during these improvements, to the Marquess of Downshire, survives. An estate map of c.1800 shows the house with its new south front, and the wing to the north that was present on the 1780 map, now gone. The third Marquess, also Arthur Hill (1788-1845), oversaw further changes to the estate. The main road to Moira ran across the south front of the house at this time and it is clear that by 1810, Lord Hillsborough was planning to re-route the road in order to enhance the appearance of his new mansion. Barry dates the opening of the new road to 1826 and it would seem that the public road in front of the house, which is depicted on the OS map of 1833, was closed between this date and 1839, when a plan showing the changes was made by Henry Murray. (Barry, p.35) Arthur Hill presided over alterations and additions to the house by Thomas Duff in the late 1820s and by William Sands, who was resident in the town during the works and for the remainder of his life, in the 1840s. A number of letters from Thomas Duff to Lord Downshire have survived that refer to works at the house between 1828 and 1830, but it is not clear from this correspondence what the nature of these was. Plans made by Henry Murray in 1833 and 1839 show that between these two dates the library was extended and given a giant portico, but Murray is unknown as an architect and it is not clear that it was he who designed the alterations. (Hillsborough Castle, p.44-5) At the time of the Townland Valuation (1828-40) the house was valued at £100 and a lengthy list is given in the fieldbook of buildings and outbuildings with their dimensions. The ‘Castle’ is captioned on the first edition OS map of 1833. William Sands, working with his relative James Sands, made several changes to the house and demesne in the 1840s, giving the house much of the appearance that it assumes today. The south front was extended to the east and a giant Ionic portico added. In order to achieve symmetry a single bay was demolished to the west. A plan of the remodelled house and some correspondence between Sands and Lord Downshire, survive. (Hillsborough Castle, p.22) In 1846, the Parliamentary Gazetteer sets out both what were perceived to be the shortcomings of the house at this time, and its charm, “Criticism has remarked that the...beauty of the town would have been greater if...the mansion, with its picturesque home-view, had been removed a little farther from the public road. Yet whatever may be said about the demesne, the town acquires an almost aristocratic air from the proximity of the mansion and seems as if caressed between the lawn and the park.” (Parliamentary Gazetteer, p.298) It appears that the valuers considered the changes made by William and James Sands to be very impressive, for by the time of Griffith’s Valuation (1856-64) the building, now referred to as a ‘castle’, is valued at £250. In 1867 the valuer notes that a new billiard room has been added to the estate, a two-storey room of cut stone measuring approximately 20x17 and this adds £15 to the valuation, bringing it to £265. The fifth and sixth Marquesses of Downshire had little connection with Hillsborough, preferring to live elsewhere. During the last quarter of the nineteenth century, Lord Arthur Hill, who was the younger brother of the fifth Marquess, lived at the Castle, managing the estates and representing County Down in parliament. The sixth Marquess of Downshire (1871-1918), who succeeded to the title in 1874 while still a small child, was by far the largest landowner in the north of Ireland at the end of the nineteenth century. However, at the beginning of the twentieth century his estates began to be sold off under the Land Acts. Given the huge reduction in the Marquess’s tenanted holdings in Down, it was perhaps felt that an estate manager was no longer necessary and Lord Arthur retired to his London house. (Purdue, p.17, 83) Following this, the house was let to Sir Thomas Dixon, son of Sir Daniel Dixon, a former Lord Mayor of Belfast who had made his fortune as a builder and timber importer. Sir Thomas succeeded his father as a Harbour Commissioner and in 1913, served as High Sheriff of County Down. Annual Revisions list Sir Thomas Dixon Bt as the occupier from 1910 and he left the house in 1919 when he purchased Wilmont, near Dunmurry. (Hillsborough Castle, p.18) In 1922 the house was purchased by the Ministry of Works in London as a residence for the Governor of Northern Ireland, a newly created post following partition. Following three years of preparation, the Duke of Abercorn took up residence in 1925, in what was then named ‘Government House’. Annual Revisions list the occupier as the Governor of Northern Ireland and the immediate lessor as the Ministry of Finance Northern Ireland from 1926. However, it appears that the Ministry of Works in London (as the Department of the Environment) retained responsibility for upkeep of the fabric of the building until 1990 when ownership passed to the Northern Ireland Office. (Hillsborough Castle, p.8, 18-9) Following a fire in 1934, the house was refurbished internally under the supervision of Roland Ingleby Smith and the gatescreen was added to the market square entrance. The Duke of Abercorn was succeeded by Earl Granville, Lord Wakehurst, Lord Erskine and Lord Grey of Naunton, the office of Governor being abolished when direct rule was introduced in 1972. Since then the house has been retained by the government for use on state occasions. (Irish Builder; Hillsborough Castle, p.19) In 1987 the Northern Ireland Minister, Tom King, set up a committee to advise on ‘the structure, decoration, furnishing and maintenance of Hillsborough Castle and the planting and maintenance of its grounds’. It was felt that the 1930s refurbishment of the house had not been entirely successful and the committee concluded that the house should reflect ‘the appearance and atmosphere of an Irish Country Mansion’ while being decorated in a manner befitting its ceremonial purposes. John O’Connell of Dublin was appointed as architect and interior design consultant and the refurbishment was completed in 1993. (Brett, p.91) References: Primary Sources 1.

Evaluation

Detached two and three-storey multi-bay Neo-classical country house on an L-plan with the west wing built c.1780 and the east wing added c.1795. Formerly one of the largest country houses in the County Down and the seat of the Marquesses of Downshire, the mansion is now in the hands of The Northern Ireland Office. Internally damaged by a fire in 1934, the house has undergone various programmes of restoration during the 20th century. Despite this it retains much of its orignal fabric externally and internally. The unusual siting of a country house in close proximity to the town of Hillsborough gives the town a distinct focal point and creates an important group with the Courthouse(HB19/05/030) and The Square(HB19/05/031-039). It is set within an impressive demesne including stableyard, formal and landscaped gardens and garden structures (HB19/05/076A-H). The mian house in enhanced by the quality of the walling, steps, balustrading and piers. With its long and significant history and located in the picturesque town of Hillsborough, the house is of significant social, political and historical importance.
