Twynholm is just a couple of miles northwest of picturesque Kirkcudbright, in the Stewartry area of Dumfries and Galloway. Its main street is flanked by whitewashed cottages, and you’ll find a range of houses to buy in this small village. Its main claim to fame is as the birthplace of Formula One driver David Coulthard, but Twynholm is also the location of the ruins of 16th century Cumstoun Castle, and a parish church which dates back to 1818.
