Ayuthaya was founded in 1350 AD by King U Thong as the second capital of Siam after Sukhothai. Throughout the centuries, the ideal location between China, India and the Malay Archipelago made Ayutthaya the trading capital of Asia. By 1700 Ayutthaya had become one of the largest cities in the world with a total of 1 million inhabitants. In 1767 the city was destroyed by the Burmese army, resulting in the collapse of the kingdom. The city was re-founded a few kilometers to the east of the ruins, which now form the Ayutthaya historical park. Most of the remains are temples and palaces, as those were the only buildings made of stone at that time.
