Lands of Borland, Barony of Cumnock, Estate in East Ayrshire, Scotland

The Lands of Borland is an estate in East Ayrshire containing the site of a former castle, a historic mill, and a chapel. The land sits on gentle slopes between Borland Smithy and the old mill location, where a small loch called Black Loch once provided water for milling grain.

The Hamilton family held the estate from around 1400 before it passed through marriage to the Montgomerys and later to other families including the Earl of Dumfries. The castle was demolished before 1855, but excavations in 1939 uncovered medieval pottery and a wooden shaft on the mound site.

The name Borland may refer to land granted to support a lord's household or possibly derive from wild boar, though the first meaning is more likely. The chapel ruins and mill remnants show how people sustained themselves through farming, grain milling, and worship on this land.

The estate is accessible for walking through open fields, with Castle Hill offering a good vantage point. Old field boundaries and paths remain partially visible and help guide you through the landscape.

The Black Loch had an unusual water flow with two different outlets, allowing trout to migrate into neighboring river systems. This natural feature made the water body particularly valuable for medieval fishing and fish migration.
