Mahasu Devta Temple

Mahasu Devta Temple stands on the Tons River at Hanol village near Chakrata, in the Jaunsar area of Dehradun district. It is dedicated to Shiva, worshipped locally as Mahasu Devta, one of the region's most sacred deities. Legend says the Mahasu were four brothers from Kashmir, sought out by the Brahmin Huna Bhatt after the demon Kirmira devoured his seven sons, and that Mahasu slew the demons at the river. Hanol is said to be named after Huna Bhatt.

Only the sanctum of the original 9th–10th-century shrine survives, with a curved Nagara-style shikhara; the mandapa and entrance hall were added later. Built of stone and wood in the Kath Kuni style, the temple has a steep slate roof crowned by a two-tiered conical canopy and kalasha, with bells hanging from the balcony corners. Only the pujari may enter the sanctum, which holds a bronze image, and only Brahmins may enter the storeroom before it. A three-day fair each August carries the deity in procession with prayers, music and dancing.
