The Khumbu valley, where Tengboche is located, came under the influence of
Buddhism about 350 years ago. Ancient scriptures of Tibet refer to this valley along with Rowlang and Khanbalung valleys as sacred places. Lama Sangwa Dorje is referred to as the founder of the oldest monastery in Khumbu at
Pangboche as well as many other small hermitages. His divine psychic knowledge and clairvoyant vision had prophesied suitability of establishing a monastery at Tengboche based on a foot print on a rock left by him while meditating. However, the actual establishment of the monastery happened only during Ngawang Tenzin Norbu's time; Norbu was considered to be Sangwa Dorje's fifth incarnation. He had established a monastery at
Rongbuk in Tibet on the northern face of
Mount Everest. He blessed Chatang Chotar, known as Lama Gulu, to found the Tengboche monastery at Tengboche village and as a result it got established at its present location in 1916. It is the first celibate monastery under the
Nyingmapa lineage of the
Vajrayana Buddhism. However, many older village level monasteries also exist close by. Three wealthy inhabitants of the local
Sherpa community are credited with funding building of the monastery. Among these three, Karma was the most influential and well known as he was a tax collector, and he also enjoyed the patronage of the Rana rulers of Nepal. It is also said that apart from Khumbu Sherpas, Sherung Sherpas have also been involved with building this monastery. Some of the village temples, chortens and smaller religious shrines are predated to 1880, particularly all the large chortens. The Mani wall, made of slabs of stone inscribed with prayers and sacred texts is dated to 1915. The monastery of Tengboche and other buildings were destroyed during the 1934 earthquake. Subsequently, Lama Gulu who had built it also died. His successor, Umze Gelden, took up the task of rebuilding the monastery, with strong support from Ngawang Tenzin Norbu. The monks and the local community, with support from a skilled carpenter from
Lhasa, re-established the monastery. Exclusive murals were painted by Kappa Kalden, a renowned artist. With an influx of tourists to the Khumbu region, particularly for trekking by mountaineers, the monastery has received wide recognition. as it is on the route to the base camp of Everest for routes made via the Khumbu icefall and west ridge. Everest expeditioners visit the monastery to light candles and seek the blessings of gods for good health and safe mountaineering.
John Hunt, the leader of the 1953 expedition and one of the first mountaineers to visit the monastery (most, but not all, previous expeditions approached the mountain from the northern (Tibetan) side), offered the following description of Thengboche in

Guru Rimpoche in the monastery was fully restored in September 2008. The entrance gate has also been rebuilt with funds provided by the Greater Himalayas Foundation based in
Washington, D.C., United States. The monastery is now said to be home to 60 monks, reflecting its financial prosperity. However, it is also said that fewer and fewer young boys join as monks as they prefer to work in mountaineering or trekking-related activities. English adventurer
Charlie Boorman and
Peter Hillary, son of Edmund Hillary visited the village in 2008. The footage was shown in Boorman's series
