The Phensang Monastery is located in the north Sikkim on the gentle slope that spreads from Kabi to Phodong. The landscape of the monastery is by every means one of the best in the entire region of Sikkim. This monastery was built in the year 1721 during the reign of Jigme Pawo, but unfortunately it was engulfed by a catastrophic fire in the year 1947. A year later, the dedication and perseverance of the lamas resulted in the monastery being rebuilt completely again.
Today, around 300 lamas of the Nyingmapa Buddhist Order reside in this monastery. Phensang hosts an annual festival on the 28th and 29th day of the tenth month of the Tibetan Calendar (usually December). Sacred dances are performed at this festival, which takes place two days before the Sikkimese New Year.
