Sangpu Neutok is an important monastery in central Tibet, just south of Lhasa, that was founded in 1072 by Ngok Lekpai Sherab, a disciple of Atiśa, and developed by his nephew, Ngok Lotsāwa Loden Sherab. It was divided in its first decades into an upper and lower monastery, each headed by its own abbot. At its height it had seven colleges, both in the Sakya and Geluk traditions, but by the mid eighteenth century, despite its fabled past, it had fallen into decline and ruin.
