Located roughly 60 metres southwest of the famous Beltany stone circle, this monument appears on early Ordnance Survey maps from the 19th century, where it was initially marked as 'Graveyard' before being relabelled 'Old Graveyard' on later editions. The enclosure measures approximately 45 metres from northwest to southeast and 30 metres from northeast to southwest, though modern maps show it as a slightly smaller penannular structure, open to the west, with maximum dimensions of 35 to 40 metres.

The site is defined by stone wall field boundaries, with its eastern edge running along the townland boundary itself. While the exact purpose of this enclosure remains uncertain, its proximity to the prehistoric stone circle suggests the two monuments may have been connected in some way. The stone circle at Beltany is one of Ireland's finest examples of Bronze Age ritual architecture, and finding what appears to be a burial ground so close by raises intriguing questions about how our ancestors used this hilltop location over the centuries.

Archaeological surveys conducted by Lacy and colleagues in 1983 noted the potential relationship between these two sites, though no excavations have definitively proven their connection. Whether the enclosure served as a burial ground for those who built or used the stone circle, or whether it represents a much later use of this significant hilltop location, remains one of the many mysteries surrounding Beltany Hill's ancient landscape.
