Niasar is a town 25 km northwest of Kashan in Isfahan province. This city, like some other cities and villages of Kashan, is the center of rose (Mohammadi) flower cultivation, and in May, you can see the traditional rose-picking ceremony here.
Niasar has a water spring called Alexander spring which creates a beautiful waterfall along its way. That is why Niasar has a green environment and many gardens.
In addition, Niasar has some historical monuments, such as the four-arched building, which is a fire temple or shrine, near the Alexander spring, related to the beginning of the Sassanid period. There are also several series of historical hand-made tunnels under the Niasar town. These tunnels are known as Reis Cave and are dug in three floors about two and a half kilometers underground. Bath and water mill are other historical monuments of Niasar.
