Ayutthaya

Founded in 1350, Ayutthaya served as the capital of the Siamese Kingdom for 417 years. At its peak (16th-17th centuries), it was known as the "Venice of the East" — a city boasting 3 palaces, 375 temples, and surrounded by three rivers. In 1767, the Burmese completely destroyed Ayutthaya. The capital was moved to Bangkok, and today the ruins of this ancient city are a UNESCO World Heritage Site.
