After passing her for many years and not really looking closely, I recently took the time to see this great monument up close . The architectural details and the great view from the top were just beautiful.
Wikipedia:The architect, Hossein Amanat, won a competition to design the monument. Built with white marble stone from the Esfahan region, there are eight thousand blocks of stone. The stones were all located and supplied by Ghanbar Rahimi, whose knowledge of the quarries was second to none and who was known as “Soltan-e-Sang-e-Iran”. The shape of each of the blocks was calculated by a computer, and programmed to include all the instructions for the building’s work. The actual construction of the tower was carried out, and supervised by Iran’s finest master stonemason, Ghaffar Davarpanah Varnosfaderani. The main financing was provided by a group of five hundred Iranian industrialists. The inauguration took place on October 16, 1971.
