Tengboche is the name of a monastery and the small village in Khumbu.
Tengboche  is the largest Sherpa monastery in the Khumbu area and exerts the greatest influence. You may join the ceremonies at the monastery, but filming or photographing is only permitted after receiving special permission to do so. Audience with the head rinpoche (abbot) can also be arranged, and these meetings are generally held in the morning.
Visit the eco-center located outside the main monastery gate. The center offers a permanent exhibition of Sherpa culture, a gift shop, and a small cinema (a film on Sherpa culture and Tengboche Monastery is shown every half hour).
Tengboche might be the first place on your trek that you have a clear view of Mount Everest. Ask one of the locals to point it out to you. Finally, every October or November, Tengboche holds the famous Mani Rimdu festival that consists of nine day's of meditation and culminates with a blessing ceremony and spectacular mask dances.
There is a bakery outside the monastery gate that serves pizza and coffee - it claims to be the highest bakery in the world, and at nearly 4,000m it is easy to believe.
There are four lodges in the field in front of the monastery. The quality and price is about the same.
