Chakhar Lhakhang:

Ahead of Jampey Lhakhang, you'll find Chakhar Lhakhang, the former palace of Indian king known as Sindhu Raja. The original palace was made of iron and was nine storeys high, holding all the treasures of the world. The current building was constructed in the 14th century by Dorji Lingpa.

There is a main statue of Guru Rinpoche along with many masks and black hats used during the Jampey Lhakhang Drup festival. Guru Rinpoche took Sindhu Raja's daughter as his consort, and you can see her wonderful statue and a photo of her footprint in the temple. You can explore the museum towards ground floor filled with religious artefacts.
