Gadong Monastery is a Geluk monastery founded in the eleventh century by Zingpo Sherapa and located in Tolung Dechen county in near Lhasa. Tsongkhapa is also believed to have meditated in a nearby cave. Gadong is also the seat of the famous Gadong oracle, a medium for one of the protector deities of Tibet called Pehar Gyelpo. The Gadong oracle lineage, unlike the Nechung oracles who are monks, is passed from father to son.
