Nay Pyi Taw has a short history. It was founded on a greenfield site near Pyinmana about 320 kilometres (200 mi) north of the old capital, Yangon. Construction started in 2002. At least 25 construction companies were hired by the military government to build the city, including Asia World and Htoo Ltd. On 6 November 2005, the administrative capital of the country was quietly relocated from Yangon to a greenfield site about 320 km (200 mi) north of where it had been, with minimal explanation from the government.The new capital’s official name was made public on 27 March 2006, Myanmar’s Armed Force day. Construction of this planned city began in 2002.
