Castle O'er

Explore this spectacular prehistoric settlement

It’s worth visiting this dramatic hill fort at any time of year to soak in the atmosphere.

Castle O’er was probably the base for an important branch of the Selgovae tribe, who ruled much of south west Scotland in the Iron Age. Archaeologists have identified the traces of nearly thirty round timber houses inside the grassy banks: when folk lived here the bank would have been topped with a wooden fence. There were at least two major phases of building at Castle O’er. At first, people built a large oval of twin ramparts and a ditch bank around the hill. Later a smaller, single-walled oval was added inside the first.

The site was probably planned as a place that would be easy to defend against attackers, but it looks as if people continued living on the hill long after it stopped being a fortress. They would have farmed livestock and crops in the rich open grasslands of the valley. Richard Bell, the local landowner, excavated part of Castle O’er in the 1890s. You can see some of the things he found in Dumfries Museum, including beads imported from Ireland, a flint blade, and Iron Age spindle whorls for spinning wool.

More information

These earthworks were the home of the Iron Age Selgovae tribe. When you reach the top of the hill, see if you can spot the circular traces of the wooden huts that once stood here. They look as if they’re arranged in a street, but some overlap others. They must date from several different periods, as the hill was occupied for a long time.
