Omagh Portal Tomb is a Neolithic megalithic monument located in County Tyrone, Northern Ireland. Dating to the fourth millennium BC, this portal tomb represents a distinctive type of megalithic burial structure characteristic of Ireland's earliest farming communities. The monument comprises a stone-built burial chamber accessed through a monumental entrance portal, constructed from massive stone slabs set upright to frame the passage into the tomb.
The site is situated upon bedrock composed of mafic igneous rock from the Ordovician to Silurian period, which would have been exposed or easily quarried by Neolithic builders. The underlying geology of this region, formed during the Silurian epoch, provided the stone resources necessary for the monument's construction, making the landscape itself integral to the tomb's creation and positioning.
The portal tomb is protected as a scheduled monument under reference 15008 by the Historic Environment Division of Northern Ireland. Such sites represent significant evidence of prehistoric territorial organisation, ritual practice and social hierarchy among early agricultural communities. The monument survives as a substantial physical record of the technological capabilities and cultural values of Neolithic Ireland.
