The altar stone is now being said not to be from Wales but somewhere further afield, likely more northerly. High barium content and not a "match" (presumably mass spectrometer) with other bluestones nor Welsh red sandstones. Also I believe the picture used may be wrong, as a previous post in talk suggests. I did not make the edit yet as nothing has been set in stone by the Aberystwyth team, will check back in the coming week Source: https://www.bbc.co.uk/news/uk-wales-67140221 — Preceding unsigned comment added by 2.29.7.19 ( talk) 21:47, 17 October 2023 (UTC) reply

Many years ago, circa late fifties, when serving with RA, friends and I passed Stonehenge many times and thought not very much about it. However the Altar stones were in place as they are today. I have now been informed that the Altar stones were placed in this position during the early fifties ?. Any info would be appreciated. thanks Des power.

Stonehenge is in Wiltshire, yes, but it is not a building. Its only roof has ever been the sky and it's never had walls. Dee Fraser 17:26, 3 August 2014 (UTC) — Preceding unsigned comment added by Dee Fraser ( talk • contribs)
