Lochindorb (Scottish Gaelic: Loch nan Doirb) is a freshwater loch about six and a half miles north of the town of Grantown on Spey, Moray, Scotland (Scottish Gaelic: Baile nan Granndach, Moireibh, Alba). On a partly manmade island on the Loch are the ruins of Lochindorb Castle, a former stronghold of the Clan Comyn. The thirteenth century castle cover very nearly the entire area of the island. It is enclosed by thick quadrilateral curtain walls, reaching nearly twenty feet in height and six feet thick. At each corner there stood round towers. Within the walls remains of a hall block, chapel and other buildings can still be identified.
