The Loughcrew Cairns, also known as the ‘Hills of the Witch’, are a group of Neolithic passage tombs dating back 5,000 years. They are situated just 3km east of Oldcastle in County Meath. The tombs are spread out over three different hills and inside Cairn T, one of the largest tombs, visitors can see a cruciform chamber, corbelled roof and stunning examples of Neolithic art. During the vernal and autumnal equinoxes, people traditionally gather at dawn to watch sunlight enter the Cairn T chamber and illuminate the interior of the tomb. The last admission to Cairn T is 45 minutes before closing.
