Loughcrew Equinox 2025 in Ireland

The ancient tombs of Loughcrew are aligned perfectly with equinox sunrise and have been a sacred place for Gaelic culture, especially during this occasion

Dates: March 20–March 21 | September 21–September 22

Equinox was a major event for ancient cultures around the world. The phenomenon occurs twice a year in March and September and means that day and night are of equal length. The ancient burial grounds of Loughcrew have always been a celestial spot for celebrating the phenomenon. Since the passage tombs are perfectly aligned with the Equinox sunrise, the beam of sunshine passes through the dark, closed tombs, creating a breathtaking view.

Brennan's Discovery

In 1980, Irish-American researcher Martin Brennan discovered that Cairn T in Carnbane East is positioned to receive the rays of the rising sun during the spring and autumn equinoxes, illuminating the artwork on the backstone. Brennan also found similar alignments at Cairn L, Knowth, and Dowth in the Boyne Valley. The alignment at Cairn T is reminiscent of the famous illumination at the Brú na Bóinne (Newgrange) passage tomb, which catches the rays of the winter solstice sunrise.

Event Highlights

Most celebrated is the Autumn Equinox, and the annual festival takes place at the location. The event starts at dawn and lasts for a day. People from all over gather to witness this phenomenon, and you often need to book a spot in advance to ensure you can see it. Among the activities that you can take part in are spiritual ceremonies, meditations, yoga, and workshops that will help you dive into the world of the supernatural and old pagan traditions.

Loughcrew Cairns

In the rich farmlands of County Meath lies the Loughcrew Cairns, a passage tomb cemetery near Oldcastle atop three hills: Carnbane West, Carnbane East, and Patrickstown. Cairn T on Carnbane East, dating to around 3000 BC, features a cruciform chamber adorned with megalithic art. During the equinoxes, sunlight illuminates the tomb's interior. Unlike the busy Newgrange, Loughcrew offers an intimate glimpse into Neolithic history, though structural issues have closed Cairn T's interior. The Hag's Chair, among Cairn T's kerbstones, served as a Mass Rock during penal times. Loughcrew, or Slieve na Calliagh ("The Hill of the Witch"), is steeped in folklore, with legends of a witch, An Cailleach Bhéara, shaping its stones.
