Though not directly on the trail, one archaeological location in Murrisk includes the following interesting Bronze Age feature, near the base of Croagh Patrick on the eastern shore of Clew Bay.
Five large stones lie directly in alignment with the sun as it comes down into a niche on the eastern shoulder of Croagh Patrick. This happens on the Winter Solstice on December 21st.
Other features here suggest this was a major ceremonial site, there are more stones surrounded by a large enclosure. Folk tales associate the site with Queen Maeve, the Celtic queen of the West of Ireland.
