Tengboche (or Thyangboche) is a village in Khumbu Pasanglhamu rural municipality in the Khumbu subregion of Province No. 1 in Nepal, located at . In the village is an important Buddhist monastery, Tengboche Monastery, which is the largest gompa in the Khumbu region. The structure was built in 1923. In 1934, it was destroyed by an earthquake but subsequently rebuilt. It was destroyed again by a fire in 1989, and again rebuilt with the help of volunteers and the provision of foreign aid. Tengboche has a panoramic view of the Himalayan mountains, including the well-known peaks of Tawache, Everest, Nuptse, Lhotse, Ama Dablam, and Thamserku. Tenzing Norgay, the first man to reach the summit of Mount Everest with Sir Edmund Hillary, was born in the area in the village of Thani and was once sent to Tengboche Monastery to be a monk. 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.
