This castle was an early home of the Black Douglases, who were the earls of Nithsdale and lords of Galloway. Not to be confused with the mansion in Threave Gardens, the castle was dismantled in the religious wars of the mid-17th century, though enough of it remains to have housed prisoners from the Napoleonic Wars of the 19th century. It's a few minutes from Castle Douglas by car and is signposted from the main road. To get here, leave your car in a farmyard and make your
way down to the edge of the river. Ring a bell, and, rather romantically, a boatman will come to ferry you across to the great stone tower looming from a marshy island in the river.
