The Khumbu valley, where Tengboche is located, came under the influence ofBuddhism 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 prophesised 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 Mt. 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
