History tells that during the 4th and 5th centuries AD, when the Gupta emperors held sway, the Kumaon hills were being governed by an independent dynasty of Katyuri kings. They selected this site for building temples. The temples originally constructed during the Gupta period were renovated by the rulers of the Ghand dynasty in the 7th century AD. Numerous temples were constructed or restored during the Gurjara Pratihara era and also in the 15th and 16th centuries.
The Mahamrityunjaya temple seems to be the oldest of all the temples and dates back to the 8th century AD. The temples of Surya, Navagraha and Neelkantheshvara are of late Katyuri age. It is said that originally four hundred temples existed here, of which only about one hundred and eight have survived
