In January 1972 a vast new monument was opened to the public in Tehran. It was called 'Shahyad' and was dedicated to centuries of Iranian royalty. Hossein Amanat was the young architect employed to design it. After the Iranian revolution of 1979 the monument's name changed, but it has remained a centrepiece for public events and demonstrations in the city. Photo: Hossein Amanat in front of his tower.
