Loughcrew, near Oldcastle in Co. Meath
Information as of 29th September 2019
Thanks to the OPW for this photo of Autumn Equinox sunrise 2019. In the 1980's Martin Brennan discovered that Cairn T receives light from the rising sun on the spring and autumnal equinox - a beam shining down the passageway and illuminating the rock art on the backstone.
Loughcrew near Oldcastle in Co. Meath, aka Sliabh na Cailleach, the Mountains of the Hag / Witch / Wisewoman / Crone.
A large complex of chambered cairns spread across the hilltops many up to 5000 years old.
The tombs are located on three different hills and Cairn T, one of the largest tombs in the complex, is situated on Cairnbane East. Inside this tomb lies a cruciform chamber, a corbelled roof and some of the most beautiful examples of Neolithic art in Ireland. During the Vernal and Autumn Equinox people gather at dawn in Cairn T to watch sunlight enter the chamber and illuminate the inside of the tomb.
