The Dingle Diamond was a temple allegedly constructed by the Tuatha De Danaan using sacred geometry in the hills of the Dingle Peninsula, West Kerry, Ireland. Built around 3000 BC it aligns with the midsummer sunrise creating an exact latitude measurement. Theories current in Archaeomythology suggest that the temple was part of a religious project undertaken by the semi-mythical people known as the Tuatha De Danaan to create a sacred marriage of the sun and the earth.
Other similar projects include Newgrange in Ireland and Stonehenge in the UK.
