Khumbu valley, where the monastery is, came under the influence of Buddhism about 350 years back.
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 footprint 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 Sangwa Dorje's fifth incarnation.
He had established a monastery at Rongbuk in Tibet on the northern face of Mt. Everest.
He blessed Chatang Chotar, known as Lama Gulu, to found the Tengboche monastery at Tengboche village.
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.
Many older village-level monasteries are 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 said that apart from Khumbu Sherpas, Sherung Sherpas have 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 was destroyed during the 1934 earthquake.
Subsequently, Lama Gulu who had built it died.
His successor, Umze Gelden, took up the task of rebuilding, 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.

However, the monastery's precious old scriptures, statues, murals and wood carvings were destroyed in the devastating fire caused by an electrical short circuit on 19 January 1989.
The monumental stone credited with Lama Sangwa Dorje's left footprint had fractured.
A few trekkers managed to salvage some books and paintings.
It has since been completely rebuilt with money donated from around the world.

Following the destruction of the monastery by fire, its rebuilding was undertaken by the present Nawang Tenzing Jangpo who is considered as the incarnation of the founder Lama Gulu, an important spiritual leader of the Sherpas.
He has established an equation with many trekkers and climbers of all denominations who visit the monastery, which has helped him in finding funds for restoration.
With due diligence to the set religious practices, the monastery has been substantially rebuilt.
Tibetan painter Tarke-la's wall paintings that display the Bodhisattvas or the Buddha decorate the sanctum.
In addition, the monks and Sherpa community with help from the Sir Edmund Hillary and Himalayan Trust, the American Himalayan Heritage Foundation and many international well-wishers have shown their support in several ways.

Hillary and Tenzing Norgay, an inhabitant of this village, were the first to reach the summit of Mount Everest on the British 1953 expedition.
Thereafter, this monastery has acquired more international interest, 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
