 The B721 road, runs through Eastrigg and other neighbouring towns and villages connecting to the nearby A75.Situated in the parish of Dornock, in the traditional county of Dumfriesshire, Eastriggs appears to have taken its name from the farm, or farm house, known as "Eastriggs" that was located in the middle of what was to become the new township.The only other buildings in the area prior to World War I were a group of houses at Lowtherton (now North Road, Lowthertown); a parallel group on what is now the B721 road; an inn and a smithy where East Road joins the B721.
