Walled Courtyard, Kelburn Castle, Fairlie

Kelburn Castle is an architecturally rich, multi-period Scottish country house of outstanding complexity and historical significance. It comprises a late 16th century Z-plan tower house incorporating earlier fabric, a long symmetrical mansion house range of approximately 1670 to 1720 linked at an oblique angle to the northwest, and a further later wing to the northeast of around 1880. A corrugated iron addition was made to the east of the tower house section around 1910.

The castle is prominently sited on the west coast of Scotland to the south of Largs, with views from the castle over the Firth of Clyde to the Isles of Cumbrae and Bute, and southwest to the Isle of Arran. The Kel Burn runs through the estate, passing through a wooded ravine and over a 15-metre high waterfall into a naturally carved pool to the southwest of the castle.

THE TOWER HOUSE

The four-storey tower house section is dated 1581 on the south wall, above a double-arched lintel that formed the former main entrance and is now a window. It has full-height conical-roofed stair-towers at the south and north corner angles, and conical-roofed turrets at the east and west corner angles. There is a corbelled garderobe projection with a small square window to the west wall, and a large wall-head stack to the north elevation. The tower has an irregular arrangement of window openings with predominantly small-paned sash window frames. Cement render was added in the 20th century, and in 2007 to 2008 this was decorated with graffiti-style murals by four Brazilian artists; this painted scheme remained in place as of 2016.

The thicker walls to the north, west and east sides of the tower suggest an earlier construction date, possibly around 1500, making use of existing structural fabric from an earlier building on the site. The building may therefore incorporate structural fabric dating to the 12th or 13th century. The Z-plan tower house was remodelled around 1580 by the then Laird of Kelburn, John Boyle.

THE NORTH RANGE

Linked obliquely to the northwest side of the tower house is the North Range, with dates of 1700 and 1722 recorded on its leadwork. It is understood to have been partly built by 1672 and extended to its present form by mason Thomas Caldwell of Beltrees and his son William between 1692 and 1700. A written agreement between Kelburn and Thomas Caldwell, dating from 1692, outlines additional works to "the new house already built." The range was built in at least two stages from around 1672 for Crown Commissioner John Boyle (died 1685) and completed by 1722 by his son David Boyle (1666–1733), lawyer and member of the Parliament of Scotland, who was created Lord Boyle of Kelburn in 1699 and later 1st Earl of Glasgow in 1703. The 1st Earl was one of the commissioners who supported and helped negotiate the Act of Union between England and Scotland in 1707.

The North Range is ten bays long and broadly symmetrical to the north elevation, with central advanced bays that are taller and gabled. It features a pedimented door piece with date panels and a two-headed eagle crest, and a distinctive twin lead rainwater pipe configuration with thistle and rose motifs. The outermost bays have crowstepped gables.

THE NORTHEAST WING

The large two-storey-and-attic northeast wing addition of around 1885, possibly by the architect William Little (1805–1894), has an asymmetrical plan with a large corbelled oriel window at first floor to the west elevation. There is a round-arched vehicular porch recess or porte-cochère at the east corner angle. It has crowstepped gables and wall-head chimneys in keeping with the earlier sections of the castle. The wing was added around 1880 for the 6th Earl of Glasgow, partly to house the then tenant and Member of Parliament for Renfrewshire, Alexander Crum. William Little, an architect and builder from Kirkcaldy who designed primarily churches and church buildings in Fife, had been commissioned by the 6th Earl to re-front Crawford Priory in Fife shortly before the addition at Kelburn was carried out.

THE COURTYARD AND GARDEN WALLS

The quadrangular courtyard of around 1700 is orientated north to south and has high rubble-built walls. A pair of tall rusticated ashlar gatepiers with ball finials flank the approach drive to the north, framing the broadly symmetrical north range additions to the castle. There are bifurcated steps with ball-finialled piers at the southwest corner. A large quadrangular-plan walled garden or pleasance adjoins to the west, with a bowed projection at its west wall. The garden courtyard, integral with the early 18th century extension of the house, was conceived to frame the new, symmetrically laid out entrance to the castle, and along with the pleasance garden and ball-finialled steps reflects the fashion for formal, classical landscape design in early 18th century Scotland.

THE INTERIOR

The interior, partly inspected in 2016, retains an exceptional and largely intact late 17th and early 18th century decorative scheme throughout the North Range, which was originally conceived as formal state apartments. This scheme is designed in a grand Baroque manner and features timber and plasterwork, pulvinated friezes, scrolled, scalloped and modillioned cornices, raised beaded panels and bolection-moulded fireplaces. Its survival on this scale is rare.

The former great dining room, now the drawing room, is particularly noteworthy. It has fluted Corinthian pilasters, a modillion cornice with an intricately ornamented frieze incorporating thistle and rose motifs, and two chimney pieces. One of these, dating to around 1700 and added in 1890, has a carved inset with the bust of a Roman emperor flanked by engaged Solomonic (spiral) columns, and a pedimented portrait frame with panelled sides. The capitals of the Corinthian pilasters are shadowed in the cove above the cornice. The impressive well stair, a form also found at Holyrood Palace, survives within the range. The plan of the state apartments carefully follows contemporary convention for sequential procession: a grand stair leads to a great dining room, then a withdrawing room, terminated by the state bedroom. The large rectangular plan drawing room has cleverly rotated its plan through 90 degrees, using the floor space created within the projecting north and south gables.

The smaller library room, the former state drawing room, to the west of the present drawing room is similarly detailed on a more modest scale. This floor is terminated by the former state bedroom, now the tapestry room.

The ground floor rooms of the 16th century tower are vaulted. The first floor contains the former great hall, now the Bastille Room, which has an elaborate chimney piece with paired spiral columned pilasters. The panelled interiors of the tower may have influenced the classically detailed new panelling in the chamber range at Rowallan Castle, which similarly received classicising improvements after being inherited by Dame Jean Mure (died 1685), John Boyle's second wife.

The northeast wing of around 1885 has a large dining room at ground floor with a mirrored-panel chimneypiece, and a billiard room above, both with Regency-style plasterwork detailing to their ceilings.

HISTORICAL CONTEXT

Kelburn is among the oldest ancestral country seats in Scotland to have been continuously inhabited by successive generations of one family, having been in the Boyle family (formerly "de Boyville") since the 12th century. The family crest and initials of various family members are represented in the stonework.

The restoration of Holyrood House by William Bruce in 1671 had a significant impact on the planning and extension of great houses and estates across Scotland, whose aristocratic owners sought to emulate the monarchy and elevate their standing through the creation of state apartments. Kelburn Castle demonstrates a decisive break with the tower house tradition in Scotland through the erection of a completely new building clearly separate from the existing tower house, conceived to provide a fine suite of state apartments which, as at Holyrood House, represented a self-conscious revival of stately royal traditions in Scotland. Like Stair House in Ayrshire and Blair Castle in Perthshire, it is a multi-period building demonstrating the transition from the medieval tower house tradition towards the Renaissance fashion for domestic, non-fortified buildings with classically inspired designs.

The 6th Earl of Glasgow inherited Kelburn in 1869, along with a significant number of other estates in Scotland, and this coincided with a significant phase of development and building improvement across the estate, including new gate lodges and gatepiers, a new gardener's cottage, gamekeeper's cottage and kennels. The 6th Earl contributed significantly to the building of a number of Episcopal churches across Scotland, but by 1888 was deeply in debt, leading to the sale of the Kelburn estate at auction. His cousin, David Boyle of Stewarton, later the 7th Earl of Glasgow, sold his own land to buy back the estate.

By 1979, the south estate offices and stables had been converted into the Kelburn Country Centre, with an information office and tea room in the old stables, a craft shop in the former laundry, and workshop areas in the old byre, among other facilities.

THE DESIGNED LANDSCAPE AND SETTING

The castle is the focal point of a coherent group of associated estate buildings and structures, including former stable offices, lodges, gates, walled gardens, sundials, monuments and estate cottages, all of which contribute to the understanding of the development of this historically significant ancestral seat over more than 500 years. The castle is set within a designated designed landscape. Before 1750 this was formally laid out on axial avenues focusing views towards higher ground to the north. Between 1750 and 1780 the layout evolved towards a more natural, informal scene, and the romantic and picturesque character of the wooded ravine and waterfall setting remains today. Some 500 acres of woodland within the estate, planted with both coniferous plantations and deciduous trees, adds further to the estate setting.

The principal phases of successive addition at Kelburn Castle, from the early Scottish Renaissance to the present day, are distinctly identifiable in the fabric of the building and represent the changing political and cultural values, as well as the economic fortunes, of Scotland within a single structure. The main phases of development demonstrate changes in Scottish architectural thought and fashion over a prolonged period, encompassing the conical stair-towers, corbels and turrets of the 16th century, the symmetrical north range and formal Scottish Renaissance details of the 17th century, and the later 19th century wing with its large first floor window disposed to take in views towards the Firth of Clyde.

The statutory address was revised in 2016 from the previously listed title of "Kelburn Castle Walled Garden Courtyard To North And Gatepiers."
