Ayutthaya Historical Park

Ayutthaya Historical Park preserves the ruins of Ayutthaya, the former capital of the Kingdom of Siam, located north of Bangkok in what is today Phra Nakhon Si Ayutthaya province. The park contains temple complexes, chedis and palace foundations that illustrate the urban layout and religious architecture of the capital from the 14th to 18th centuries.

Key monuments include Wat Mahathat with its iconic Buddha head entwined by tree roots, Wat Phra Si Sanphet on the former royal palace grounds, and several other wat complexes and prang towers arranged across the island formed by river channels. The site is organized for visitor circulation and interpretation across multiple temple ruins.

Ayutthaya was founded in 1350 and served as Siam’s capital for several centuries before its capture and destruction by Burmese forces in 1767, after which the capital was relocated. The surviving ruins in the park date primarily from the 14th through 16th centuries and reflect the city’s historical importance as a regional polity and trading center.

The park lies on the river island formed by the Chao Phraya and its branches, roughly north of Bangkok and commonly reached by road or river from the capital; the historic island’s compact layout makes it practical to visit multiple sites in a single day.

• Founding and fall: Founded as the capital in 1350, the city was sacked by Burmese forces in 1767; the park preserves the island-city's ruins laid out within a river loop.
• Visitor logistics: The site is a UNESCO World Heritage Site and is best explored by bicycle or tuk-tuk across the island of the old city to visit multiple temples in one day.
