CHAHAR TAQI: Also called Chahar Qapu, it is a square fire-temple of stone and gypsum with an area of 586.60 square meter, which belongs to the Sassanian period and is considered to be the greatest of its kind in that epoch. It is a square structure with a domical roof, and there seem to have existed some corridors around it. The building bears perfect resemblance to the Sassanian temples. Its main facade is over 16 meters wide. This is one of the historic sites heavily (up to 90%) damaged during the Imposed War of Iraq against Iran. (1980-88).
