Cyrus the Great and تخت جمشید, in Baghdad

The Iranian Embassy in Baghdad Iraq has recently been in the news as a result of a bombing. Less has been focused on its unique design. This structure is based on the columns of Persepolis during the rule of Cyrus the Great, and invokes a Persian Neo Classical design. Admittedly I am unaware if this genre of architecture exists as a term, but it does now. I have  found very little written on the subject and history of the structure. I have put a small piece I have in my collection of the original stone work for reference.
