Bloak Holm mill was located nearby, a little further down the Glazert Water and is recorded as being part of the Kirkwood Estate in the 18th century. The surviving Aiket millstones are made of French Burr which came in sections and the millwright had to turn these into a usable millstone. The sections were shaped and then the pieces of the jigsaw puzzle such were fitted together to give him the overall shape and size required. Once assembled, a set of iron tyres were fitted around them, in exactly the same way as a wheelwright would prepare a wooden wagon wheel. When cold, the metal tyre is made a little too small to fit around the stones, but when heated expansion caused it to become just large enough to drop into place. The cooling metal attempts to shrink back to its original size, gripping the pieces of the stone tightly. The stones were sealed with plaster of paris, poured into every crack and the working face was also coated to help cement the stones together, and to keep the dirt out. This hill, its name meaning the 'Bracken Crag', lies about a mile and a half from Dunlop. It is said to be the site of the death of one of the Cunninghames of Aiket, killed by a Montgomerie during the times of the feuds between these families. The area is now known as the 'Brechna Braes.' The gardens have been thoroughly developed, using recycled stone for steps, landscaping of the old quarry and extensive ornamental tree and shrub plantings. In 2011 the castle was put on the market for £1.1 million. Notes;  Sources;
