It's interesting to note the site we visited to day existed before the pyramids. It also predates Stonehenge in England. Thought to date back to 4500 BC it was considered by historians to be a place of enormous importance. According to Dr David Clarke, former keeper of Archelogy, National Museums of Scotland it was possibly one of the main power centres of Europe.
Fotunately the site was found to be in remarkably good condition, with stone walls and interior furnishment surviving almost intact, as you can possibly see from the photos.
The individual houses were all linked by passages to form what was thought to be a close knit farming community with evidence of an adjoining workshop.
Later, I am standing alongside one of the standing stones of the Ring of Brodgar. Originally it was a 60 stone circle of which only 36 remain.
