The interior is equally impressive. Kumbum means 100,000 images in Tibetan. Indeed, there is what seems to be an endless series of tiny chapels. Each chapel is decorated with wall paintings, some have various statues of Buddhas, Bodhisattvas and deities. Most paintings date to the time of the construction of the stupa.
There are nine levels, 108 cells and 75 chapels. At the higher levels you can go out to an outdoor terrace and enjoy an incredible view on the town, monastery and surrounding fort.
