Nightlife of Qazvin

 1-Sado saltaneh Bazar
Qazvin bazar with its 1000-years old architecture is one of the interesting sites in Qazvin.  If you have seen the markets of Isfahan and Shiraz, visiting Qazvin Bazaar reminds you of the architecture of those markets. Most of the beautiful decorations in this market are special examples of brickwork and tiling. In this market, in addition to shopping, you can watch the architectural art of past centuries.
•    Imamzade Shazde Hossein
The holy tomb of Prince Hussein, son of Imam Reza (AS) who died in 201 AH. It is one of the most important shrines and places of interest in Qazvin, which has always been of interest to the people since the third century. This building is of special importance with its unique architecture and tiling and mirror work.
We suggest the best time for visit there in the evening.
