About the demesne
The Stewarts came to this stretch of the Ballinderry in the seventeenth century, and James Stewart built the first Killymoon house here in 1671. What stands today is a replacement: the earlier house burned, and in 1803 a new castle went up to a design by John Nash.
Nash is the reason the building is worth crossing a field to look at. He is the architect of Regent Street and the Royal Pavilion at Brighton, the man who gave London much of its stucco confidence — and Killymoon is one of his early ventures into the castellated style, all round towers, gothic windows and picturesque silhouette. He designed the entrance gates too. The story runs that Nash took his fee in some unusual form; like a lot of estate stories it is repeated more often than it is documented, so treat it as a good tale rather than a fact.
The demesne around the house was laid out to be looked at — parkland running down to the river, a hanging wood on the far bank, an estate bridge over the Ballinderry, a sawmill working the water. That planned landscape is still legible when you walk Cabin Wood, even though the estate has been broken up: the castle is a private home, much of the parkland is now Killymoon Golf Club, and the wood belongs to everybody.
That last part is the good news. Sixteen acres of an eighteenth-century demesne, two rivers, bluebells in spring and a Nash castle across the field — free, open at all times, ten minutes from the middle of Cookstown, and reached down a farm track most people drive past.
