Chagpori was the site of the monastic medical college of the same name founded there by Sangye Gyatso in 1696. This medical college, which incorporated a recently restored temple made by Thang Tong Gyalpo, was supplied with revenue generating lands and with a constant stream of students by a "monk tax". It remained an important medical institution in Tibet and Central Asia up until the mid-Twentieth century.
