Tchoga Zanbil is a nice and interesting pyramid but in my taste not so wonderful. I guess it depends on the people, one of my friend found it memorable, one of the best place in Iran ; it's not my own opinion.

The real positive point for me is that is the only heritage of the Kingdom of Elam. What is rare is precious.

This site just looks like a big "ziggurat" (pile) of bricks more or less recently arranged. It is, but some of these bricks are carved of an ancient writing, probably restored.

To conclude, it's a very interesting place which deserves its inscription, but I make express reservations due to a kind of non-authentic place.
