The early 15th-century Chamba Lhakhang was one of a trio of Maitreya ("future Buddha") temples built in Leh by King Draspa Bum-lde. The obvious centrepiece is a colorful, oft-repainted three-story Buddha. However, the more unique features are original medieval mural fragments between the inner and outer walls (look left as you enter).
Getting in is a hit-and-miss affair. This is often one of the sights covered on an Old City Heritage Walk.
