Stongdey Monastery, often written Stongde, Stongday, Tonday or Thonde, is a flourishing Buddhist monastery in Zanskar, Ladakh, northern India, approximately 18 km north of Padum, on the road to Zangla. The gompa was founded in 1052 by Naropa's disciple, the famous translator Lama Marpa Lotsawa (1012-1097). It was taken over by the Gelugpa about four centuries later and became dedicated to Je Tsongkhapa. There are seven temples in all. The Tshogs-khang is decorated with exquisite painting including some with deities on a black background outlined in gold.
