01 Tynron Doon has been described as the most important iron-age fortress in the Dumfriesshire and there is reputed to be a spectre of a headless horseman associated with the hill. There is a way marked route up onto it from the Penpont to Tynron road (parking at NX817933). There was an L-shaped tower house built on the top of Tynron Doon as late as the latter half ot the 16th century. Finds from the site and the surrounding slopes have a wide date-range and some of these can be seen in Dumfries Museum.

On the skyline near the left edge of the picture is Queensberry Hill and below it you can see the village of Thornhill which lies on the A76 Dumfries to Kilmarnock road. Penpont village is nearer and more towards the centre of the picture.
