Newgrange - The sun entering the passageway at Winter Solstice. Newgrange is a prehistoric monument in County Meath, Ireland, about one kilometre north of the River Boyne. It was built about 3200 BCE, during the Neolithic period.
Passage in Newgrange Megalithic Tomb. At sunrise on the mid-winter Solstice, a shaft of sunlight pierces the narrow opening above the entrance. Slowly, light travels the passage and illuminates the chamber.
On a hilltop near Doagh is a Bronze Age megalith known as The Holestone. Couples used to promise marriage by clasping hands through the hole in the stone. from Irish: Dumhach, meaning "mound") Photo by George Pennock Photography.
