Naypyidaw, officially romanized Nay Pyi Taw (; nèpjìdɔ̀ Royal Capital), is the capital and third-largest city of Myanmar. The city is located at the centre of the Naypyidaw Union Territory. It is unusual among Myanmar's cities, as it is an entirely planned city outside of any state or region. The city, then known only as Pyinmana District, officially replaced Yangon as the administrative capital of Myanmar on 6 November 2005; its official name was revealed to the public on Armed Forces Day, 27 March 2006. As the seat of the government of Myanmar, Naypyidaw is the site of the Union Parliament, the Supreme Court, the Presidential Palace, the official residences of the Cabinet of Myanmar and the headquarters of government ministries and military. Naypyidaw is notable for its unusual combination of large size and very low population density. The city hosted the 24th and 25th ASEAN Summit, the 3rd BIMSTEC Summit, the Ninth East Asia Summit, the 2013 Southeast Asian Games and the 2014 AFC U-19 Championship. Naypyidaw is Burmese for "abode of the king", and is generally translated as "royal capital", "seat of the king", or "abode of kings". Traditionally, it was used as a suffix to the names of royal capitals, such as Mandalay, which was called Yattanarbon Naypyidaw (). Naypyidaw was founded on a greenfield site near Pyinmana, about north of the old capital, Yangon. Construction started in 2002 and was completed by 2012. At least 25 construction companies were hired by the military government to build the city. It is estimated that the planned city development reaches US$4 billion. On 6 November 2006, more than 12,000 troops marched in the new capital in its first public event: a massive military parade to mark Armed Forces Day, the anniversary of Burma's 1945 revolution against the Japanese occupation. Filming was restricted to the concrete parade ground, which contains enormous sculptures of Kings Anawrahta, Bayinnaung and Alaungpaya.
