Ayuthaya Kingdom, Once declared the most magnificent city on earth, Ayuthaya was an impressive site, with three palaces, more than 400 temples and a population that reached nearly 1,000,000. In 1767, the Burmese attacked and conquered Ayuthaya however and the capital was moved to Bangkok. The ruins of Ayuthaya are now a major attraction for those visiting Thailand. It is just 80 km (50 miles) north of Bangkok, and is easily reached by train, boat, bus or van.
