Gyantse is a small agricultural town famous for its woolen carpets & the Phalkor Chorten. Amongst the Lamasery & the fort, this unique structure built in 1414 AD consists of five stories representing the five steps to enlightenment, topped by thirteen rings, which symbolize the stages of advancement towards Buddhahood. There are 108 halls inside, each with frescoes & Buddha shrines, the frescoes showing a strong Indian influence. Before 1959 traders coming from Kalimpong & Gangtok used to enter Tibet through Yandong and then to Gyantse, en route to Lhasa.
