The monument consists of an Iron Age hillfort situated on a knoll on the S slope of Grennan Hill, about 250m from the summit.

The fort is oval on plan. The inner area is 46m E-W by 24m. This is enclosed by a deep ditch on the N and W and by very steep slopes elsewhere: almost vertical on the E side. The ditch is up to 11.5m wide and 3.5m deep. Outside it is a bank up to 0.8m high. The ditch has a low internal rampart on the W side. Neither ditch nor rampart is continued on the E side, where the vertical rock face appears to have been adequate defence, nor is the ditch very pronounced on the S side.

The entrance has been on the NE side, entering the fort at a diagonal angle to the ditch and bank. Two level areas about 5m in diameter within the interior may be the sites of circular houses contemporary with the fort. The area to be scheduled is approximately oval, measuring a maximum of 95m NW-SE by 70m, to include the fort and its outer defences, as marked in red on the accompanying map.

Statement of National Importance

The monument is of national importance as a fine example of a small Iron Age hillfort, which well illustrates the use of natural topography to minimise necessary defensive works. It has the potential, through excavation and analysis, to provide important information about prehistoric defensive architecture and domestic economy.



RCAHMS records the monument as NX 89 NW 7.

About Scheduled Monuments

Historic Environment Scotland is responsible for the designation of buildings, monuments, gardens and designed landscapes and historic battlefields. We also advise Scottish Ministers on the designation of historic marine protected areas.

Scheduling is the way that a monument or archaeological site of national importance is recognised by law through the Ancient Monuments and Archaeological Areas Act 1979.

We schedule sites and monuments of national importance using the criteria published in the Historic Environment Scotland Policy Statement.

The description and map showing the scheduled area is the legal part of the scheduling. The additional information in the scheduled monument record gives an indication of the national importance of the monument(s). It is not a definitive account or a complete description of the monument(s). The format of scheduled monument records has changed over time. Earlier records will usually be brief and some information will not have been recorded. Scheduled monument consent is required to carry out certain work, including repairs, to scheduled monuments. Applications for scheduled monument consent are made to us. We are happy to discuss your proposals with you before you apply and we do not charge for advice or consent. More information about consent and how to apply for it can be found on our website at
