Cairn T at Loughcrew passage tomb cemetery is aligned on the Autumn and Spring equinoxes, one of which falls on Tuesday 20th. On that day and those around it the sun shines down the passage and illuminates the back recess and the stunning megalithic art that decorates it.

O.P.W. staff are in attendance at the cairn today (from 7.15 - 8.30 am), tomorrow and Tuesday; so this morning I dragged myself out of bed at 5.30 a.m. and made the trip. We arrived about 7.30, fifteen minutes after sunrise but didn't get into the chamber for another half hour. I can't say it wasn't worth the wait though and with the absoloutely perfectly clear sky we got a spectacular experience. Check out some pics above and a time-lapse video of a previous equinox below.
