Glencullen in County Dublin marks Andromeda.
The quartzite Glencullen megalith is one of those special quartz megaliths, all of which represent a special style that I assign to one ancient artist, thinking that one particular cave - e.g. such as Kents Cavern - was the origin of the quartz stones, where they were also sculpted and then transported. Perhaps the geologists will one day be able to determine the origin of the quartz stones, or at least check if they could have a common quarry origin.
Glencullen represents Andromeda and the megalith has Andromeda cupmarked as well as Cassiopeia above it. The reverse, back side of the megalith shows a vase and above that the stars of Boötes, which is exactly opposite in the sky. Below Boötes the constellation Ophiuchus seems to be marked as a figure.
There is a side view of the stone as well but this was not helpful for the decipherment.
