Thimphu (Tibetan alphabet: ཐིམ་ཕུག་, Dzongkha: ཐིམ་ཕུ་), also spelled Thimpu, is the capital and largest city of Bhutan. It is situated in the western central part of Bhutan and the surrounding valley is one of Bhutan's dzongkhags, the Thimphu District. The city became the capital of Bhutan in 1961. As of 2005 it had a population of 79,185, with 98,676 people living in the entire Thimphu district.
The city is spread out longitudinally in a north-south direction on the west bank of the valley formed by the Wang Chuu, also known as the Thimphu Chuu River. Thimphu is located at 27°28′00″N 89°38′30″E / 27.46667°N 89.64167°E and is spread over an altitudinal range between 2,248 metres (7,375 ft) and 2,648 metres (8,688 ft). Although unusual for a capital city, Thimphu is not served by an airport, but relies on the airport at Paro, connected by road some 54 kilometres (34 mi) away.
