Rivash (Persian: ريوش) is a city in the Central District of Kuhsorkh County, Razavi Khorasan province, Iran, serving as capital of both the county and the district.[2]
According to the evidence, this area was inhabited before the advent of Islam, and due to the fact that the old road of the southern cities of Razavi Khorasan to Tehran passed through this area, it has been more prosperous in the past. One of the most important historical events is the Mongol invasion, which after the occupation of Nishapur, due to its impassability and the large number of snakes in the area, Mongol horses and soldiers could not pass through this area and escaped its bite.
