Look at the roofs, the black and white picture is a photo taken from Tehran's municipality more than 60 years ago, this beautiful building was located at the northern side of "TOUPKHANEH" square, the biggest square in the old Tehran and now located at the south east of the city. The building destroyed about 40 years ago and now you can find out a bus terminal at its location.
The colored pictures are from a modern tower located at Bucharest St. (an expensive commercial place at the center of the city). Carefully look at the roofs. It seems the architect took the idea of the roof right from the municipality building but I am not sure about it, it could be an accident or maybe both came from another building from other place in the world. If you know more about these roofs please let me know.
