Undoubtedly Keyvan’s most important project remains lighting for the first time the ruins of Persepolis and Hafezieh for the inauguration of Shiraz art festival in 1967. As he was called only two weeks ahead he did not have any other choice than using the studio projectors not adapted for outdoor lighting, but it did not rain and he achieved his goal. He used over 800 flames lined over the walls, paths and around the mausoleum of Hafez during the festival, which remained as a breathtaking image every year for thirteen years. Unfortunately we possess only one image!

While studying in Rome he designed architectural lighting shades and they were exhibited in a famous decorative art gallery “Da Myricae”, del Babuino street in Rome in 1965.

The lighting of   UNESCO‘s   audithorium, Keyvan’s favorite design of Piere-Luigi Nervi, was his gift to M. Jalali, the chief of iranian delegation for his fairwell ceremony in 2006.
