Bangkok was established as Thailand's capital in 1782. Over the next two centuries, it developed in many ways reflecting the modern dynamism; however, its ancient glories were well maintained, especially in the old areas around the Grand Palace. Today, Bangkok has become the principal gateway and prime tourist attraction for both domestic and international travellers. Bangkok occupies a total area of 1,568 square kilometres on a flat alluvial plain divided by the Chao Phraya River. Composed of about 50 districts (Khets), it is home to one-tenth of the country's population. Thon Buri, a former capital, is now a district under the administration of the Bangkok Metropolis.
