Just visited this site http://www.ancient-wisdom.co.uk/portocromleqdosalmendres.htm called Almendres near Evora Portugal.
The earliest parts are dated to 6000 BC and its the oldest stone circle in the Iberian Peninsula.
Thought it was about time we had a thread on ancient sites on TBs so here it is.
... pics I took of this site.
Post something about a site that has impressed you.
