The Phra Nakhon Si Ayutthaya or Ayutthaya in short, is one of Thailand's historical and majestic highlights. Serving as the Thai capital for 417 years (1350 1767: Kingdom of Ayutthaya), it was once glorified as one of the biggest cities in Southeast Asia. During the 17th century, most foreign visitors to Ayutthaya, traders or diplomats alike, claimed Ayutthaya to be the most illustrious and glittering city that they had ever visited. The map of Ayutthaya published in 1691 by Simon de la L oubere in Du Royaume De Siam is proof of such recognition.

The Kingdom of Ayutthaya reached its apex in terms of sovereignty, military might, wealth, culture, and international commerce in the 16th century when the Kingdoms territory was extended far beyond present-day Laos, Cambodia, and Myanmar. Ayutthaya even had diplomatic relations with Louis XIV of France and was courted by Dutch, Portuguese, English, Chinese and Japanese merchants.

Visitors can explore and appreciate Thai history in Phra Nakhon Si Ayutthaya, which is situated only 86 kilometers north of Bangkok. Visitors to Ayutthaya can marvel at its grandeur reflected through numerous magnificent structures and ruins concentrated in and around the city island surrounded by Maenam Chao Phraya, Maenam Pa Sak and Maenam Lopburi. More importantly, Phra Nakhon Si Ayutthaya Historical Park, an extensive historical site in the heart of Ayutthaya city, has been included in UNESCO's World Heritage list since 13 December, 1991.

The Past
The Kingdom of Ayutthaya was built and developed in leaps and bounds. The ruins in Ayutthaya that survived the test of time embody both the glorious and ignominious stories of the Kingdom.

This ancient capital of the Kingdom of Ayutthaya, founded in 1350 by King U-Thong, had thirty three kings of different dynasties and reached its peak in the middle of the18th century. A magnificent city with three palaces and over 400 magnificent temples on an island threaded by canals Ayutthaya was truly an impressive city that attracted both Europeans and Asians. After a 15-month siege the Kingdom of Ayutthaya was conquered and completely destroyed by the Burmese in 1767. When King Taksin the Great finally liberated the Kingdom, a new dynasty was established and the capital was moved to Thonburi.
