The Tengboche Monastery
Rebuilt after a 1989 fire, Tengboche Monastery is the largest and most significant in the Khumbu, following the Nyingma school of Tibetan Buddhism, and hosts the Mani Rimdu festival each autumn. The current structure dates to the early 1990s, funded partly by international mountaineering expeditions that had passed through and received blessings before Everest attempts.
The best panorama on the standard route
On clear afternoons, Everest, Nuptse, Lhotse, and Ama Dablam are all visible from the monastery courtyard, a view many trekkers rate above even the Base Camp approach itself, since Tengboche sits at a wide-open bend in the valley rather than hemmed in by closer ridgelines.
Mani Rimdu festival
Mani Rimdu, held over several days each October or November depending on the lunar calendar, features masked dances performed by monks re-enacting the triumph of Buddhism over pre-Buddhist Bon traditions. Trekkers on an autumn itinerary occasionally catch part of the festival by coincidence, though it is not scheduled around trekking traffic.
Etiquette
Remove shoes before entering the monastery, walk clockwise around the building and any nearby chortens, avoid touching a monk's head or robes, and ask before photographing ceremonies or individual monks.
The approach from Namche
Reaching Tengboche from Namche Bazaar involves a steady 420 m net climb over roughly 10 km, including a descent to cross the Dudh Koshi before the final ascent through rhododendron forest, a genuine day's effort rather than a short add-on stop.
Founded in 1916 by Lama Gulu
Tengboche Monastery was built in 1916 by Lama Gulu, a disciple of the 10th Dzatrul Rinpoche of Rongbuk Monastery across the border in Tibet, which Tengboche still regards as its mother monastery. Three wealthy members of the local Sherpa community funded its construction, most notably a tax collector named Karma who held the patronage of Nepal's ruling Rana family at the time.
Destroyed by earthquake in 1934, rebuilt by hand
The 8.1-magnitude Nepal-Bihar earthquake of 1934 collapsed the monastery's main temple completely. Lama Gulu, then 85 years old, died shortly afterward, but Khumbu villagers rebuilt a larger structure themselves within a few years using local labour and resources, decades before the 1989 fire that led to the version standing today.
