Castlelaw is a hill that rises steeply from the valley to the northern tops of the Pentland Hills in Midlothian, Scotland. It is best known for the Iron Age hill fort on its slopes. When it was occupied the site consisted of three earthwork ramparts, ditches and timber palisades. The fort also contained a Souterrain for the storage of agricultural produce.
The fort commands views over the Forth and Lothian. Traprain Law and Berwick Law, both significant centres of power in the Iron Age, are also visible from the site.
The fort is maintained by Historic Environment Scotland as a scheduled monument.
The military training area comprises Castlelaw Ranges and Dreghorn Dry Training Area. It borders Edinburgh and lies within the Pentland Hills Regional Park, a total of 775 hectares. Castlelaw Ranges are situated on the south side of Castlelaw Hill. Dreghorn Dry Training Area extends from the Edinburgh City By-Pass at Dreghorn Mains to Flotterstone and from Bonaly Reservoir to Fulford. The area is dominated by three peaks, Allermuir, Capelaw and Castlelaw which rise to heights of 493m, 454m and 488m respectively.
The highpoints of the training area give stunning views across the city, the Firth of Forth and on a clear day the Highlands beyond. The area is home to some rare habitats and wildlife including small numbers of black grouse.
