Hurlstone, county Louth
H 943 876 - Sheet 36
Nearest town: Ardee
The hole is 20 cms in diameter, splaying to about 25 cms.
This part of Louth used to be rich in standing-stones, and The Hurl Stone is one of a chain of stones
possibly forming some kind of boundary - though equally it might be the only remnant (a perforated door-slab) of a wedge-tomb.
