Nalendra, a monastery located north of Lhasa in Penyul, was founded in 1436 by Rongton Mawai Sengge, who was born into a Bon family and studied at Kadam monasteries. The monastery was absorbed into the Sakya tradition and Rongton Mawai Sengge came to be considered one of the six jewels of the Sakya tradition. There are extensive ruins at the site, along with a renovated assembly hall containing murals. Khenpo Tsultrim Gyelsten is credited with initiating the renovation of the site.
