Mangbro Monastery is located above Kewzing Bazaar, South Sikkim and was established in 1790 A.D. by a Lama named Athyok Lama. The old structure, which had been damaged by an earthquake, was demolished and a new monastery was erected in its place in the year 2003.There is a big rock with a tree growing upon it. This rock has a foot imprint on it which is believed to be of Guru Rinpoche. There exist eight old stone stupas near the gonpa. They are believed to have been built by the lamas to ward off evil spirits from this area. This monastery follows Nyingmapa Sect.
