(Payvand Iran News)

On 7 March 2019, parts of Taq Kasra collapsed only two years after the completion of a conservation operation by Avers. The Czech firm had been commissioned by the Iraqi Ministry of Culture. Taq Kasra, also known as the Arch of Ctesiphon, is the world`s largest brick vault and the symbol of the Persian Empire in the Sasanian era (224-651 AD). The monument is located about 35 km south of Baghdad, in modern-day Iraq, which was, at the time, part of Persia. -TaqKasra.com
