I am pretty sure this isnt Crete, this is the Agora of Athens and to be precise this is called Stoa of Attalos. It houses the museum of the Ancient Agora. This is at the center of Athens(Thiseio) and it is a very popular tourist destination.
I thought it looked like the stoa in the forum in Athens since it looked like new beams and such, but wondered if I missed a different reconstruction in Crete. Thanks!
