ANCIENT INVISIBLE CITIES
Istanbul

 

Using 3D-imaging technology, Professor Darius Arya brings Istanbul’s tumultuous history alive in his examination of one of history’s most iconic buildings: the Hagia Sophia. Built by the Romans, this Christian cathedral survived 1,500 years of earthquakes, riots, sieges and conquest to become a mosque and now a museum.

Hagia Sophia: Istanbul’s Ancient Mystery

 

Istanbul’s magnificent Hagia Sophia has survived on one of the world’s most active seismic faults, which has inflicted a dozen devastating earthquakes since Hagia Sophia was built in 537 AD. As Istanbul braces for the next big quake, a team of architects and engineers is investigating Hagia Sophia’s seismic survival secrets. NOVA follows the team’s discoveries as they examine the building’s unique structure and other ingenious design strategies that have insured the dome’s survival. The engineers build a massive eight-ton model of the building’s core structure, place it on a motorized shake table and hit it with a series of simulated quakes.
