Killymoon Castle Cookstown, County Tyrone, was built in 1802-3 for Colonel James Stewart MP, to the designs of John Nash. Colonel Stewart's family had held the property since 1634.
He had obtained plans for a new house incorporating parts of the old one, which had been destroyed by fire ca 1800, from the Dublin architect, Robert Woodgate, however in 1802 he was replaced by Nash.
Nash exhibited two drawings for his scheme at the Royal Academy in 1802.
Killymoon was Nash's first castle in Ireland, and reputedly cost £80,000 to build.
It was described in the Irish Penny Journal of 1841 as "one of the most aristocratic residences in the province of Ulster", with state apartments consisting of "a breakfast-parlour, dining room, ante-room and drawing-room, all of which are of noble proportions and their woodwork of polished oak".
When sold in the 1880s the details of the sale referred to the demesne being almost entirely surrounded by a wall of 10 to 12 feet in height, the demesne being entered by four lodges and avenues, containing two stone quarries, a huge quarry and kiln, a gravel pit, labourers' cottages, and two ornamental cottages; a walled garden and kitchen gardens, with lawns and ornamental shrubberies; vineries, peach and fig houses; a conservatory, stove, mushroom and forcing houses, potting sheds, tool houses, two excellent gardeners' dwelling houses, and an ice house.
This park was clearly approved of by Sir Joseph Paxton, who wrote:
I have visited most of the celebrated country seats in the Kingdom and a very large number on the continent, and I have never seen one - for the extent of it - more compact, more perfect in itself, or where the highest natural beauties have been more aided by refined taste and judgment, than Killymoon.
This demesne was, in 1922, nevertheless, decimated and sold off in lots, mostly for its timber.
Part of it is now used as a golf course.
The gate lodges and the two gardeners' houses no longer stand; the conservatory is ruinous; though substantial 18th century outbuildings, for farm use, and an 18th century saw mill remain intact, close to the castle.
Colonel James Stewart was an absentee client for Nash and much of the supervision of the new castle fell to his wife.
She is known, through surviving correspondence, to have been discussing the design of two cottages with Nash as late as 1805.
For his part, Colonel Stewart is notorious for having 'lost' his new castle in a night's gambling, but the next day the winner, the Prince Regent (later GEORGE IV), told him he could keep his "little cabin" in Ireland.
In 1850 the property was sold, following the decease of William Stewart, who was a bachelor, and was bought by the Moutray family.
The present owner's family bought it at the break-up of the estate in 1922.
TODAY'S CASTLE has a romantic silhouette in a splendid location above the Ballinderry River with a back-drop of sweeping woodland and parkland.
The principal front is dominated by an almost central battlemented, machicolated round tower and turret; at one end, an octagonal tower with similar features; and at the other end the profile of the square tower in the adjoining front, the base of which is arched to form a porte-cochére.
The latter tower has slender, octagonal corner turrets with cupolas.
The windows are pointed, grouped together under segmental hood mouldings, which Nash and his ilk regarded as being Saxon. There is good interior planning with square, circular and octagonal rooms fitted together.
The hall has a double staircase and is lit by a Gothic lantern on a plaster, fan-vaulted ceiling.
The Library is in the form of a Gothic chapel, with stained-glass windows.
Extensive stables, out-houses and labourers cottages were built on the demesne, and on completion of the residential quarters Colonel Stewart had the 585 acres of the Killymoon demesne enclosed by a wall 10 to 12 feet high.
Entrance to the demesne was by way of four stone lodges and avenues at various points along the boundary wall.
The Killymoon estate remained the property of the Stewart family for six generations; however, their extravagant lifestyle caused the Stewart family to fall on hard times, especially during the years of the Irish famine.
The Killymoon estate was sold in 1852 for £100,000.
In 1857, the castle had again been sold to the Cooper family; and, in 1865, Colonel Bolton, an English gentleman, purchased the castle.
A mere ten years later, Mervyn Stuart Thomas Moutray JP, became the owner of Killymoon Castle until 1916, when Gerald Macura bought the castle and town of Cookstown for almost £100,000.
By 1918, Macura was also in financial difficulties and was compelled to sell off his assets.
Hence, in 1922, John Coulter bought the castle and grounds for the princely sum of £100.
Today the castle remains the home of the Coulter family.
In addition, situated on what was previously some of the castle’s estate lands, is an 18-hole golf course.
