Cromlech is a portal tomb located near Omagh in County Tyrone, Northern Ireland. Portal tombs are among the earliest megalithic monuments, built during the Neolithic period by farming communities who migrated to Ireland around 4000 BC. They consist of large stone slabs arranged to create a chamber, typically with two substantial portal stones flanking the entrance, and were constructed to serve as communal burial places for the dead.
The site sits on bedrock of Ordovician Extrusive Rocks, mafic lava and tuff formed over 450 million years ago during the ancient volcanic activity that shaped this part of Ulster. The local geology would have provided the builders with suitable stone for their construction, though the massive capstones and uprights may have been selected or transported from specific sources nearby. Like other portal tombs, Cromlech would originally have been covered with an earthen mound, which has since been eroded away, exposing the stone skeleton that survives today.
The monument is protected by the Historic Environment Division under reference 14437, ensuring its preservation as a significant archaeological record of Neolithic settlement and burial practice in the Omagh area. Portal tombs remain among the most impressive surviving monuments from prehistoric Ulster, their sturdy construction allowing them to endure for nearly six thousand years.
