The 12th-century Jame Mosque of Yazd is still in use today. The mosque is an exemplification of Persian architecture. It is crowned by a pair of minarets, the highest in Iran, and the portal's facade is decorated from top to bottom in tile work, predominantly blue in colour.
The two towering minarets dating back to the Safavid era. They also served as a sort of a lighthouse to guide the travelers in the dessert.
Uppersia suggests you to travel to Yazd in Fall or Winter in order to visit the historical places at best as it is not crowded in those seasons and you can enjoy the pleasant weather.
