The clear planning concepts that have been established within the 'Structured Plan' are: the Tashichheo Dzong, Wang Chuu and the streams, Green Hills and their Forest cover, monasteries, temples, chortens and prayer flags, the urban core, urban villages and the urban corridor. The southern entrance of the city at Simtokha Dzong anchors the city limits with the Northern and Western limits of the Wang Chuu Valley.
