Thailand's capital city was founded in the eighteenth century after the fall of the old capital, Ayutthaya. The new capital, Thonburi, was established on the west bank of the Chao Phraya River where it had once been a small trading town known as Bangkok, originally developed following the arrival of the Portuguese in the fifteenth century. Later, a French mission built a fort there in the seventeenth century. In 1782, the new King of Siam, Rama I, founder of the present Chakri dynasty, built his palace and moved the administration to the east bank of the river. He gave the capital the new name Krung Thep, meaning "City of Angels". However, foreigners continued to refer to it as Bangkok. In the 1980s, Bangkok transformed itself into a global metropolis due to the Asian investment boom, and convinced multinational corporations to make the city their regional headquarters. Bangkok charmed visitors to visit and revisit. Since then, the city has had a major impact on regional finance and business, and an increasing influence on global politics, culture, fashion and entertainment. The Bangkok Metropolitan Administration is divided into 50 districts, each with its own registered residents. The Greater Bangkok area has a population of 15 million and is 1,562.2 sq km in size. It is a special administrative area with an elected governor and is the country's economic centre, where every bank's headquarters is located. Bangkok is also the seat of UN agencies and international organization, such as the Secretariat of the UN Economic and Social Commission for Asia and the Pacific (ESCAP) and the International Committee of the Red Cross (ICRC). Bangkok has been the perfect host for many events, and has won numerous awards and recognition. Since 2005, Travel + Leisure magazine has voted Bangkok one of the top cities for seven consecutive years, ranking it as the World's No. 1 city three times and Asia's No.1 city six times.
