The name Ayutthaya derives from the Sanskrit word Ayodhyā, found in the Ramayana, which means "the invincible [city]". Grammatically, this word is composed of the morphemes a- 'not' + yodhya 'defeatable' (from the root yudh- 'to fight') + ā, a feminine suffix.


Phra Nakhon Si Ayutthaya, covering 2,557 square kilometres (987 sq mi)[2], is on the flat river plain of the Chao Phraya River valley. The presence of the Lopburi and Pa Sak rivers makes the province a major rice farming area. The province is one of only 10 provinces with no forests.[5]

Ayutthaya was founded in 1351[a] by King U-Thong. It was the capital of Thailand (then called Siam) for 417 years from 1351 until it was sacked by the Burmese army in 1767. During this era, now usually referred as the Ayutthaya period or Ayutthaya kingdom, Ayutthaya was ruled by 33 kings of five different dynasties. The kingdom became a major regional player, and a trade center of the East, a meeting point of European merchants and Asian traders. Notable monarchs during the Ayutthaya period include King Naresuan the Great, who liberated Ayutthaya from the first Burmese occupation and embarked on a reign of conquest, and King Narai the Great, who initiated diplomatic relations with France, during the reign of Louis XIV. His reign was the golden age of trade and culture.

The city was strategically positioned. During several months of the year, the flood plains around the cities would be flooded by the many rivers around the city. Enemy sieges were thus impossible, and forced to withdraw. This advantage was a contributing factor in the many failed Burmese invasions.

The ruins of the old capital in the Ayutthaya historical park have been a UNESCO World Heritage Site since December 1991. The province is also home to the Bang Pa-in summer palace complex.

Originally named Krung Kao (กรุงเก่า), the province was renamed Phra Nakhon Si Ayutthaya in 1919.[6]

According to legend, King Ramathibodi I found a beautiful conch shell buried in the ground, and chose the site as the place for his capital. He then placed the shell on a pedestal tray and built a pavilion around it. The seal shows this pavilion with the provincial tree behind it.

The provincial flower is the ดอกโสน (RTGSdok sano) Sesbania aculeata, and the provincial tree is the fragrant manjack (Cordia dichotoma). The provincial slogan ราชธานีเก่า อู่ข้าวอู่น้ำ เลิศล้ำกานท์กวี คนดีศรีอยุธยา can be translated as "Old capital city, food larder of the country, poets laureate galore, and national heroes".


Honda has an automobile factory in the province. Honda produces hybrid electric vehicles (HEVs) and batteries for electric vehicles there, and at its factory in Prachin Buri. Honda's Ayutthaya factory has an annual capacity of 300,000 units.[7]

Ayutthaya is 76 kilometres north of Bangkok and boasts numerous ruins. Such ruins indicate that Ayutthaya was one of Indochina's most prosperous cities. The Ayutthaya Historical Park is a vast stretch of historical sites in the heart of Ayutthaya city.

There were three palaces in Ayutthaya: Grand Palace, Chantharakasem Palace or the Front Palace, and Wang Lang or the Rear Palace.
