I very nearly bought a cottage in Sligo a couple of years ago that has a portal tomb about 60m from the front door. I got gazumped on it though by someone with (probably) no interest in the monument itself. Bah!
I used to go sit on these when I was a stressed-out teenager and chill a while...both in Mrs Bygraves garden, the Addington stones were then open to the road so there was no fence-climbing to do.
