It was founded at 1379 and is important for the whole tibetan nation because was the birth place of Tsonkahapa, the founder of the yellow sect gelugpa. There's so many temples, estupas and mandalas but is one of the monasterys more controled by the chinese goverment. It's a shame because is full of chinese tourist and you can not find the nice tibetan ambience. anyway, is important for their history. Tikets are 85 yuan.
