Эспи Мазгат

Espi Mazget, meaning "White Mosque" in Talysh, is a historic sanctuary in the Dinachal rural district of Paresar, in Iran's Gilan Province. It stands on the western bank of the Dinachal River, about 80 km west of Rasht and 22 km south of Talesh (Hashtpar), and falls within Rezvanshahr County. The site is of pre-Islamic origin: the mosque was raised on the location of a fire temple dating to the Sasanian era. Its architecture is associated with the Seljuk period, and the building is inscribed on the Iran National Heritage List.

The site's origins lie in the pre-Islamic period. A fire temple was built here in the Sasanian era, and a mosque was later established on the same spot. The mosque was completed in the Seljuk era, and the sanctuary continued to be used in both the Seljuk and Safavid periods.

According to tradition, the building was a large fire temple that was converted into a mosque after Islam spread through the region, from the 3rd century AH onward, and prayers were held there for a long time.

It was added to the Iran National Heritage List on 7 October 2000 and is administered by the Cultural Heritage, Handicrafts and Tourism Organization of Iran.
