This monastery is located above Mangan Bazaar, the North district head quarters, is a Lepcha monastery known as ‘Rigon Rigdzin Tharling Gonpa’ popularly known as Ringyim Gonpa. The great Terton Sangey Lingpa mentions this Gonpa in his book. It is written that this location bears the footprints of Guru Padmasambhava and is bounded by a cave in the north dedicated to the diety Hayagriva (Tadrin) and spring of Dakini (Khadui Thukhang) in the South. Thus, the site for the Gonpa was selected because of its sacredness.

     The foundation of this Gonpa is laid on a rock bearing the footprint of Lord Guru Padmasambhava. In order to preserve this rock, a  wall is constructed on the right side across this rock. A portion of the rock can therefore be seen inside the Gonpa. It follows Nyingmapa sect of Buddhism. It was built in 1852 during the reign of seventh Chhogyal Tsugphud Namgyal (1785-1864). The monastery was damaged by an earthquake in 1981 and was  renovated in 1985 with government aid. It also functions all the major ceremonies throughout the year.
