Ayutthaya, full name Phra Nakhon Si Ayutthaya, is an ancient capital and modern city in the Central Plains of Thailand, 85 km north of Bangkok.
Ayutthaya was originally founded in 1350 and over the next few decades developed to be the capital of the Siamese Kingdom. Ayutthaya became the second capital of Siam after Sukhothai.
Ayutthaya is like an island surrounded by three rivers that act as natural barriers for defense. In addition, the rivers brought large and small boats from other important towns in the kingdom and from other nations to engage in commerce. Ayutthaya was both the administrative and the economic center of the kingdom and was filled with a great diversity of people from different areas.
