Thirlestane Castle

Thirlestane Castle is an outstanding domestic castle of exceptional architectural and historic significance, built between 1587 and 1590 with major additions and alterations by Sir William Bruce and Robert Mylne in 1673, and further additions and remodelling by William Burn and David Bryce between 1841 and 1845. It stands on low ground beside the Leader Water, by the town of Lauder, and is remarkable for its singular scale and complexity.

The building comprises a 16th century I-plan keep with later Renaissance and Scots Baronial additions to the north and south, forming a roughly symmetrical T-plan overall. The composition is dramatically vertical, with a turreted roofscape dominated by a central ogee-roofed tower. The 16th century core is built predominantly of sandstone rubble with pink Bassendean sandstone ashlar dressings, defined by corner towers, intermediate turrets, and oversailing wall-walks behind balustraded parapets. The Scots Baronial additions to the north and south use squared and snecked greywacke sandstone rubble with long-and-short ashlar dressings, and are characterised by castellated oriel windows, pedimented dormers breaking the eaves, and swept-roof towers with ball finials.

The west, or principal, elevation features a balustraded entrance stair flanked by outsized urns, rising to a terraced entrance court. A six-storey ogee-capped tower occupies the centre. Rounded towers advance to the left and right, corbelled out to square at the fifth floor and flanked by two-stage circular turrets at the corner angles. Corbelled balustraded balconies link the towers at the third and fifth floors, with advanced pyramidal and swept-roof towers flanking. The north wing is characterised by a gated service court with segmental-arched covered walkways at ground and first floor levels. The south wing features a single-storey, five-bay, segmental-arched conservatory and garage with an advanced two-stage bell-tower to the centre, set on a raised balustraded court.

The east, or rear, elevation of the 16th century section is four storeys high with eight bays. Corner towers to the east are corbelled out to a square plan at the upper level, with crow-stepped gables linked by a balustraded balcony. The corner towers to the west have been incorporated into the 17th and 19th century remodelling. On the north and south elevations, six semicircular towers project at intervals with intermediate turrets to the centre, and oversailing wall-walks run behind balustraded parapets.

Windows throughout are predominantly fitted with 12-pane timber sash and case glazing. There is a variety of tall, coped end and ridge chimney stacks with clay cans. Rainwater goods are cast iron.

The interior combines a Jacobean and Scots Baronial decorative scheme, with some exceptional 17th century Carolingian elements retained. A timber-panelled entrance hall leads to an elaborate processional suite of public rooms extending the full length of the main body of the castle. On the ground floor, the panelled room, billiard room, and library feature bolection-moulded oak panelling, red granite chimneypieces, and compartmented plaster ceilings. The state apartments at first floor level — the Ante Drawing Room and Dining Room — retain elements of the 17th century decorative scheme, dominated by intricately detailed and thematically conceived plasterwork ceilings executed by George Dunsterfield and John Hulbert in 1674–75. These are among the finest plasterwork ceilings of their kind, and may surpass those by the same craftsmen at the Palace of Holyrood in Edinburgh. The 19th century Jacobean staircase incorporates oak panelling dating from the 1670s. Chimneypieces throughout are of yellow Sienna marble, supplied by David Ness of Edinburgh, with plain marble chimneypieces on the upper floors. The service quarters include a large groin-vaulted coal house adjacent to the kitchen.

The Eagle Gates and boundary walls form part of the listed structure. The gatepiers are of channelled ashlar, square in plan and capped with eagle statuettes, with ornamental cast-iron gates and swept quadrant walls flanking. Evidence of a former single-storey, L-plan lodge survives within the stonework behind the quadrant wall to the east. Circular iron gateposts with shallow conical caps mark the west, or stables, entrance. Coped rubble walls bound the estate to the north, south, east, and west.

The historical significance of the castle is considerable. A motte-and-bailey castle first occupied the site in the 12th century, little of which appears to survive in the later fabric. Between 1548 and 1550, the English built a short-lived Italianate artillery fort on the site. Work on the earliest section of the present residence began in 1587, commissioned by Sir John Maitland, Chancellor of Scotland, who was created Lord Maitland of Thirlestane in 1590. His descendant John Maitland, later Duke of Lauderdale, employed Sir William Bruce for the 1673 Renaissance additions. These works included the advanced pavilion wings — originally ogee-roofed — to the principal elevation, the raised terrace, the classical doorpiece, and the grand entrance stair. The eminent Scottish architect Robert Adam prepared two proposals for remodelling before 1790, but neither was carried out. The 9th Earl of Lauderdale, who succeeded to the property in 1839, commissioned William Burn to provide a new suite of rooms, incorporating the old corner tower and adjacent pavilion into the new wing. Burn planned and supervised the works between 1840 and 1844 at a final cost of £25,000. His alterations included corbelling out the west corner turrets once more, restoring them to their original form. The 19th century Scots Baronial additions, attributed to Burn and possibly David Bryce, include the ogee-roofed central tower, the swept spirelets of the north and south wings, and the service court. David Bryce had joined William Burn's office in 1825 at the age of 22, and by 1841 had risen to become Burn's partner. Bryce subsequently added the conservatory to the north wing. The influential Maitland family were landowners in Lauderdale from the 13th century, and their descendants continue to reside at the castle.

The castle is also closely associated with the development of the Royal Burgh of Lauder, which preserves much of its original medieval plan form, with two back lanes — one of which, Castle Wynd, demarcates the eastern boundary of the castle — and a main street centred on the old Tolbooth.

Following the establishment of a trust spearheaded by the National Heritage Memorial Fund, a critical programme of conservation was undertaken between 1978 and 1982 by Crichton W. Lang, with further repairs completed by David Willis in 1993. Consolidation and restoration work was ongoing at the time of the listing update in 2008, principally at upper and attic interior levels, which were then unoccupied.

The 16th century structure is distinguished by its innovatively long east–west plan form, its large rounded towers at each corner, and its semicircular wall towers connected by broad oversailing parapeted wall-walks. These are particularly important survivals and represent a unique contribution to Scotland's domestic architecture of the period. The castle is listed in a group with Castle Wynd, Hume Lodge including the boundary wall to the north and west; East High Street, Wyndhead Stables Lodge; Thirlestane Castle Estate, Garden Cottage; Thirlestane Castle Estate, Stables Offices; and Thirlestane Castle Estate, Walled Garden.
