Sess Kilgreen is a decorated standing stone and the remains of a passage tomb, a Neolithic megalithic monument dating to around 3500–2500 BCE. Located near Dungannon in County Tyrone, the site sits on bedrock formed from the Tyrone Group, a geological sequence of limestone, mudstone, sandstone and siltstone laid down during the Visean period. The passage tomb represents a form of communal burial practice characteristic of Neolithic Ireland, in which the dead were deposited in a stone-built chamber reached via a narrow passage, all originally enclosed beneath an earthen mound.
The decorated standing stone at Sess Kilgreen is of particular archaeological significance, as carved designs on megalithic monuments of this period are relatively uncommon. Such carvings—typically abstract motifs including cup marks, spirals or geometric patterns—offer insight into the ritual and symbolic practices of Neolithic communities.
The monument is now protected by the Historic Environment Division of Northern Ireland under reference 15510, recognising its importance as evidence of early settlement and ceremonial activity in the Dungannon area. Though reduced to fragmentary remains, Sess Kilgreen contributes to understanding the distribution and character of passage tombs across the island of Ireland.
