Why visit Castle Kennedy Gardens?
Castle Kennedy Gardens are on a grand scale. They lie on the Lochinch estate between the Black Loch and the White Loch, with the ruined 17th-century Castle Kennedy at one end and the Victorian Lochinch Castle at the other. The bones of the garden are the formal layout made by the 2nd Earl of Stair in the 1720s, inspired by the gardens of Versailles, so expect long vistas, avenues and large shaped landforms.
The Earl used his troops to shape the ground, and their earthworks still have names: the Giant's Grave, Mount Marlborough and the Dancing Green. Walk through these and the scale of the design becomes clear. The garden is well known for its monkey puzzle avenue and for rhododendrons, many of them very large. Thanks to the Gulf Stream and the sea on two sides, the climate is mild enough for rhododendrons and other plants not often seen growing in Scotland, and there is also a walled garden to explore.
For gardeners the interest is twofold: the chance to see an early 18th-century formal design on the ground, and the range of tender shrubs that survive in this sheltered corner of Galloway. Restoration of the gardens is ongoing, so there may be new work to see on each visit. Allow plenty of time, as the walks around the lochs are long, and bring sturdy footwear.

The story behind the garden
Castle Kennedy was built in 1607 as a mansion house by the Earl of Cassilis, on the site of an older castle. In 1677 the estate was acquired by Sir John Dalrymple, later Earl of Stair, but the house burned down in 1716. The 2nd Earl kept the ruin as the focal point of new formal gardens laid out between 1720 and 1730, based on what he had seen as ambassador at Versailles. He used troops to reshape the land, creating features such as the Giant's Grave, Mount Marlborough and the Dancing Green.
Over time the gardens fell into disrepair. In the 1860s the 9th and 10th Earls built Lochinch Castle in a Franco-Scottish style and partly restored the 18th-century layout. The estate still belongs to the Earl of Stair, and restoration of the gardens continues.
