Thimphu

A dzong is a former fortress, now used for multiple governmental and religious functions.

From Wikipedia:

Dzongs serve as the religious, military, administrative, and social centers of their district. They are often the site of an annual tsechu or religious festival.

The rooms inside the dzong are typically allocated half to administrative function (such as the office of the penlop or governor), and half to religious function, primarily the temple and housing for monks. This division between administrative and religious functions reflects the idealized duality of power between the religious and administrative branches of government.
