To the west of the road leading to the National Museum is Dumtse Lhakhang, an unusual chorten-like temple that was built in 1433 (some sources say 1421) by the iron-bridge builder Thangtong Gyalpo. The temple was built to subdue a demoness and so is chained firmly to the ground. Its three floors represent hell, earth and heaven, and hold some of the finest murals in Bhutan. It's essential to bring a good torch. Your travel agency may need to have Dumtse listed on your permits, so mention you'd like to stop here in advance.
Beyond Dumtse Lhakhang, to the east of the road, the tiny Puna Lhakhang is said to date from the 7th century.
