This place is amazing, what surprises me most is they seem to have done a decade's work on it since they found it a month ago ?
I was going to say it looks for all the world a later city built on top of an even older city. on digging a little deeper that is exactly the case.
A 5000 year old city on top of a 7000 old city. which is explained on this Livescience website I provided.

Edited Forgot to mention how it reminds me of the ness of brodgar.
