The monument comprises a fort of late prehistoric date, visible as cropmarks on oblique aerial photographs.

The monument lies mainly in arable land, at about 95m OD, on the edge of a naturally defensible SE facing scarp, overlooking Dalry Burn. It comprises the remains of a defended settlement of Iron Age date, oval in shape, measuring approximately 100m NE-SW by 70m transversely, enclosed within the ploughed-out remains of a double bank and ditch.

From the ground, only a short stretch is now visible on the NW side, whilst from the air, the bank, ditch and remains of 4 internal palisade ditches are clearly visible. Monuments of this type are largely associated with the Iron Age, although an earlier Bronze Age date cannot be ruled out.

The area to be scheduled comprises the remains described and an area around them within which related material may be expected to be found. It comprises an irregularly shaped area, a maximum of about 150m SW-NE by 100 SE-NW, as marked in red on the accompanying map extract. The timber stable in the field is specifically excluded from the scheduling.

Statement of Scheduling

The monument is of national importance because of its potential to contribute to our understanding of prehistoric settlement and economy, with particular reference to defensive sites. Its importance is increased by its proximity to other monuments of potentially contemporary date.
