Chhundu Lhakhang is located eleven kilometers north of Haa. It is one of the several sites dedicated to the local deity App Chhundu.
App Chhundu is said to have been banished to Haa by Zhabdrung after an altercation with Ap Gyenyen, the local deity of Thimphu. He was also involved in a fight with the local deity of Paro, resulting in the deity stealing water from Haa, which is why no rice is grown in Haa. To this day, Haaps make their annual offering to App Chundu, keeping true to their Bon past.
