Historical and cultural studies on historic monuments in Tafresh, Markazi province, will begin soon, Iranian Cultural Heritage News Agency reporte.

Preliminary information provided by archeologists show that Tafresh dates back to the era of the Medes.

The city is situated to the north of Arak and ranks second after Saveh in terms of historical monuments, director-general of provincial Tourism and Cultural Heritage Department said.

Seyyed Mohammad Hosseini told Cultural Heritage news agency that the present location of Tafresh is within the territory once governed by the Medes, Achaemenids and Partians.

"Many cultural and historic monuments from the Sasanid era to post-Islam period, including the Safavid, Zandieh and Qajar are still located in Tafresh," he added. Hosseini asserted that Markazi Tourism and Cultural Heritage Department intends to draw up a cultural and historical ID for the province's historic monuments and provide researchers with a more precise account of the era to which the monuments belonged. "The research will also determine the era the Zoroastrian clerics of Tafresh belonged to," he noted.
