To the southwest of the Ulster city of Derry in County of Donegal, near the town of Raphoe, is a Neolithic Celtic monument known as the Beltany Stone Circle. The Beltany Stone Circle is estimated to have been constructed approximately 5000 years ago based on recent archeological research funded by the Irish Heritage Council. Dating Beltany from about 3000 BC makes this monument older than Stonehenge and the Egyptian pyramids (some published sources conversely date the construction of the stone circle at between 1300 and 800 BC).
This is a Neolithic stone circle of about 147 feet in diameter made up of in excess of sixty remaining stones. The name is linked to the Celtic Beltane fire and fertility festival and the site is thought to date to about 2000BC.
