Lamayuru or Yuru Monastery (Tibetan: བླ་མ་གཡུང་དྲུང་དགོན་པ་, Wylie: bla ma gyung drung dgon pa "Eternal Monastery", Urdu: لمیرو گومپا) is a Tibetan Buddhist monastery in Lamayouro, Leh district, India. It is situated on the Srinagar-Leh highway 15 kilometres (9.3 mi) east of the Fotu La at a height of 3,510 metres (11,520 ft).
A. H. Francke states that, "according to popular tradition," it was originally the foremost Bon monastery in Ladakh; its name means sauwastika and is a popular symbol in Bon for "eternity". Yungdrung is the name of the most popular school of Bon. It is currently affiliated with the Drikung Kagyu school of Buddhism.
The Drikung history states that the Indian scholar Naropa (956-1041 CE) allegedly caused a lake which filled the valley to dry up and founded Lamayuru Monastery. The oldest surviving building at Lamayuru is a temple called Seng-ge-sgang, at the southern end of the Lamayuru rock, which is attributed to the famous builder-monk Rinchen Zangpo (958-1055 CE). Rinchen Zangpo was charged by the king of Ladakh to build 108 gompas, and certainly many gompas in Ladakh, Spiti Valley and the surrounding regions, date from his time.
The gompa consisted originally of five buildings, and some remains of the four corner buildings can still be seen.
Lamayuru is one of the largest and oldest gompas in Ladakh, with a population of around 150 permanent monks resident. It has, in the past, housed up to 400 monks, many of which are now based in gompas in surrounding villages.
Lamayuru is host to two annual masked dance festivals in the second and fifth months of the Tibetan lunar calendar, when all the monks from these surrounding gompas gather together to pray.
Nearby is Wanla Monastery.
