The historic second capital of Thailand, then known as the Kingdom of Ayutthaya, was founded in 1350. Glorified as one of the biggest cities in Southeast Asia and a regional power for some 400 years, it reached its apex in terms of military might, wealth, culture, and commerce in the 16th century, when the Kingdomâ€™s territory extended into and beyond present-day Laos, Cambodia, and Myanmar. Ayutthaya had diplomatic relations with Louis XIV of France and was courted by Dutch, Portuguese, English, Chinese and Japanese merchants. Conquered by Burmese invaders in the late 18thÂ century many of the cityâ€™s magnificent structures were almost completely destroyed and the ruins which remain were abandoned after a new king liberated the Kingdom and moved the capital to Thonburi, across the river from modern-day Bangkok. A UNESCOâ€™s World Heritage site, the ruins of Ayutthaya are today one of Thailandâ€™s archaeological highlights, with three palaces and over 400 temples strategically located on an island surrounded by three rivers connecting the city to the sea. The architecture is a fascinating mix of Khmer and early Sukhothai styles. Some cactus-shaped obelisks, called prangs or reliquary towers, denote Khmer influence and look something like the famous towers of Angkor Wat. The more pointed towers, called stupas, are ascribed to the early Sukhothai influence. And everywhere you look there is praise to Buddha.
