The Four Stone Circles and Alignment at Omagh is a Bronze Age ceremonial complex comprising four distinct stone circles arranged in alignment. Located in County Tyrone, Northern Ireland, the monument is situated on bedrock of Neoproterozoic age—specifically an unnamed mafic igneous intrusion formed during the Neoproterozoic period. This dark crystalline geological foundation has endured for over 600 million years, providing a stable platform for the Bronze Age builders who constructed their circles here roughly 4,000 years ago.
The arrangement of four circles in linear progression is uncommon in the British Isles and suggests a landscape designed for complex ceremonial purposes. The stones themselves would have been sourced from the local igneous bedrock or glacial deposits, shaped and positioned to create sight-lines and gathering spaces for ritual activity. The alignment of the circles indicates sophisticated understanding of geometry and the surrounding topography.
The monument is protected by the Historic Environment Division of Northern Ireland under reference 14564, recognising its significance as an exceptional Bronze Age ritual site. The complex survives as a rare example of multi-circle ceremonial architecture and contributes substantially to understanding Bronze Age social organisation and spiritual practices in the North of Ireland.
