Situated on the summit of Arbory Hill, which is itself the W spur of the ridge of higher hills to the E, this is one of the higher forts in Scotland. Its defences reveal at least three phases of construction, in which an inner stone-walled enclosure has been inserted into the interior of a larger bi-vallate fort, which has itself replaced an earlier palisaded enclosure. The inner enclosure, which is roughly circular and measures 43m in internal diameter (0.14ha), was defended by a substantial wall, now spread up to 9.8m but probably originally in the order of 3m in thickness, and has entrances on the E and SW. This occupies the centre of the earlier fort, the interior of which measures 82m from E to W by 69m transversely (0.42ha). The earlier defences comprise two stone ramparts, each with an external ditch accompanied in places by a counterscarp bank; the inner of these ramparts forms a bank about 5.2m in thickness, standing no more than 0.8m in height internally, but up to 3m above the bottom of the ditch. The two lines are roughly concentric about 5m apart around the southern half of the circuit, but diverge to 8m on the NW, and as much as 20m on the ENE, to form the outer terminal of the staggered entrance in the outer rampart on the E. This is one of five entrances that penetrate both ramparts, the others being on the S, W, WNW and N respectively, but whereas the inner and outer gaps of those in the NW quadrant are roughly opposed, on the E and S the gaps are offset to expose the righthand side of approaching traffic; while these latter may be an expression of defensive architecture, they may also hint that the inner and outer ramparts of the outer circuits are not contemporary, the outer enclosing an overall area of 0.88ha. The evidence of the earlier timber perimeter is most clearly seen at the E entrance, where a minor outward deviation in the line of the inner rampart to create a slight stagger at the gap has revealed the line of the earlier palisade trench, which is otherwise mainly buried beneath the rampart round the rest of the circuit. Within the outer ramparts there are traces of the stances of at least seven timber round-houses, three of which had internal ring-ditches and lie within the inner enclosure.

First depicted in 1773 on Charles Ross's A map of the Shire of Lanark (1773), and thereafter on William Forrest's map of The County of Lanark from an Actual Survey (1816), it appears in slightly more detail on the 1st edition OS 6-inch map (Lanarkshire 1864, sheet 43). In 1889 it was sketch-planned by David Christison (Christison 1890, 302-4, fig 6). A chert scraper was found here in 1931 (Proc Soc Antiq Scot 66, 1931-2, 18). In 1959, the fort was surveyed by RCAHMS and in 1963 and 1975 revisited during the preparation of the County Inventory for Lanarkshire (RCAHMS 1978, 90-1, no.213, fig 45). It was visited by the OS in 1978. A prominent hill in Clydesdale adjacent to Roman monuments, it has been regularly photographed from the air, by CUCAP in 1945, 1949 and 1968, and by RCAHMS in 1976, 1980, 1982, 1985, 2000, 2003 and 2006. The palisades, along with adjacent cord rig, were first identified from photographs taken under snow in 1980. It was Scheduled in 1967
