I visited this site in February 2012. Floods occurred a few months ago and some traces are still viewable, however the authorities are working to preserve the splendor of the place.

The historic center of Ayutthaya was founded during the 14th century and became the capital of the Ayutthaya kingdom. The capital was destroyed by Burmese armies and given up since the end of the 18th century. Nowadays, the historic site consists of numerous buildings, more or less well preserved, scattered throughout the city and out. This site is one of the better examples of the Thai art and of a Southeast Asian ancient city. Not too far from Bangkok (two hours by van), it's possible to visit major sites in one day or two.
