No posts survive, no stones mark the ground. What archaeologists found in 2006 were eleven post-holes, the ghostly impressions left in the earth by upright timbers that once formed a circle roughly eight metres across. Arranged in pairs, with a gap of between one and a half and one and three quarter metres between each, the posts framed an entrance porch or avenue on the south-eastern side. A single post stood at the centre. The whole structure faced outward towards an elevated landscape with open views towards Tory Hill to the east, and further still to the west and south, a positioning that seems unlikely to have been accidental.

The circle was uncovered not through targeted archaeological investigation but as a consequence of road construction. Excavation took place under licence in advance of the N9/N10 Kilcullen to Waterford Road Scheme, and what emerged was far more than anyone had anticipated. The timber circle sat within a cluster of related structures, themselves part of a substantial area of previously unknown prehistoric activity ranging in date from the Early Neolithic through to the Late Bronze Age, a span of perhaps three thousand years of intermittent human use of this plateau. Charcoal recovered from the entrance area of the circle was radiocarbon dated to between 1043 and 918 cal BC, placing its construction and likely use firmly in the Late Bronze Age, a period when timber circles, which were roofed or unroofed circular enclosures defined by large wooden posts set into the ground, served ceremonial or communal functions that archaeology can identify but rarely fully explain. The date range puts the circle broadly contemporary with the final phases of activity at sites like the Irish Navan Fort complex, though Scart appears to have operated within a much more localised landscape of use and memory.
