Shabestan of Jama Masjid of Tabriz-as Tabriz does not have a hot climate, the Shabestan here was not built underground.

A shabestan or shabistan (Persian: ????????; Old Persian xšap?.st?na) is an underground space that can be usually found in traditional architecture of mosques, houses, and schools in ancient Iran.

These spaces were usually used during summers and could be ventilated by windcatchers and qanats.

During the Sasanian Empire and the subsequent Islamic periods, "shabestan" also referred to inner sanctums of the shahs where their concubines resided. Later these structures came to be called ?????? zan?neh (feminine residence), ???????? andaruni (inner private zone) and ???? haram (from Arabic harem).
