In short: For centuries, Ayutthaya was a global titan of commerce and diplomacy, a cosmopolitan metropolis positioned perfectly between India and China. Yet, despite its advanced hydraulic engineering and strategic river defenses, the great Siamese capital was razed to the ground by the Burmese army, leaving behind only monumental ruins.

Founded around 1350, Ayutthaya served as the second Siamese capital after Sukhothai. The city was a masterpiece of hydraulic engineering, utilizing a systematic grid of roads, canals, and moats. Its location on an island surrounded by three rivers was a deliberate strategic choice: the site sat above the tidal bore of the Gulf of Siam, which protected the city from sea-going warships, while the river network provided a sophisticated water management system that was unique in the world.

At its peak, Ayutthaya was one of the largest and most cosmopolitan urban areas on Earth. By 1600, its population was approximately 300,00 and may have reached 1,000,000 around 1700. This wealth and diversity were fueled by its position as a global trade hub, connecting the East and West. The Royal Court exchanged ambassadors with far-reaching powers, including the French Court at Versailles, the Mughal Court in Delhi, and the imperial courts of Japan and China. The city's architecture reflected this globalism, assimilating styles from Persia, Europe, India, and Japan into its unique school of art.

The era of glory ended abruptly in 1767 when the Burmese army attacked and razed the city, burning it to the ground and forcing its inhabitants to flee. The city was never rebuilt in its original location. While the new capital was later established downstream at Bangkok, its builders consciously attempted to replicate the urban template and architectural splendor of Ayutthaya. Today, the 289-hectare World Heritage site stands as an extensive archaeological landscape, characterized by massive Buddhist monasteries and towering prang reliquary towers.
