History of Chungthang
Chungthang has great historic significance, especially when it comes to the history of the dissemination of Buddhism in the state. According to legend Guru Padmasambhabwa {Buddhist Guru} considered to be the first preacher of the Budhhist faith in this region first came to Chungthang at Sikkim. He rested on a rock and left his footprint on it. Around the rock some paddy is grown, which is supposed to be a miracle as the terrain of the region is not at all conducive to the growth. Lepchas form the major ethnic group among the inhabitants of Chungthang. Local people earned their livelihood on these paddy fields until the Army was deployed there.

It is believed Guru Nanak visited this place during his trip to China and Tibet. He had dug his walking stick in a particular place which eventually grew into a tree. The tree has trunk in stick shape and leaves are below the rounded trunk which appears to be the handle of stick. An amrit kund was also constructed there. Guru Nanak visited the place during his third udasi in order to solace the Karma pa Nying ma pa sect then being hounded out from Tibet by the Ge lug pa sect. according to history Guru Nanak during one of his journeys with his disciples, had come across this place and vanquished two demons. The footprints of that battle were believed to be still left on that cordoned off rock. It is also said that Chungthang is derived from the Punjabi word , "Changa sthan" meaning good place, which was bestowed by Guru Nanak.
