townland of Navan. It is on a low hill about west of Armagh (at grid ref. area H847 452). The site consists of a circular enclosure in diameter, marked by a large bank and ditch encircling the hill. The ditch is on the inside, suggesting the earthwork was symbolic rather than defensive. Inside the enclosure two monuments are visible. North-west of centre is an earthen mound in diameter and high. South-east of centre is the circular impression of a ring-barrow, about in diameter. Construction and early history Flint tools and shards of pottery show activity at the site in the Neolithic (c. 4000 to 2500 BC). In the eighth century BC (Bronze Age), a ring of timber poles was raised at the western site, where the high mound now stands. It was 35m in diameter and surrounded by a ring ditch with an eastern entrance. This ditch was in diameter, wide and deep. In the fourth century BC (Iron Age) a new wooden structure was built on the same spot. It was a round building attached to a bigger round enclosure, making a figure-of-eight shape, both with eastern entrances. The larger ring of the figure-of-eight was in diameter, the smaller about . The smaller building had a hearth. The structure has been interpreted as a roundhouse with an attached yard or pen, or a building with an attached enclosure for rituals. Finds suggest that at this time the site was occupied by someone of high standing such as a king, chieftain or druid. They include a chape, a finely-decorated pin and the skull of a Barbary monkey, which was likely a pet that was either imported or given as a gift. The structure was rebuilt several times over the following centuries. In the first century BC, a huge timber roundhouse-like structure was built on the same spot. It was 40 metres in diameter and consisted of an outer wall and four inner rings of posts (probably holding up a roof), which circled a huge central pillar. This oak pillar has been dated by dendrochronology to the year 95 BC and could have stood about 13 metres tall. The building had a western entrance, toward the setting sun, which suggests it was not a dwelling. A ditch and bank were dug around it. There is evidence that the huge ditch and bank that encircles the hill was dug at about the
