Knockroe Passage Tomb

Knockroe Passage Tomb is a Neolithic passage tomb in County Kilkenny, Ireland, about 10 km north of Carrick-on-Suir. The larger western chamber is aligned so that sunlight at sunset during the winter solstice shines along the passageway.[1] Notable megalithic artwork decorates many stones lining the passage, and quartz is scattered throughout the site.[2]
