Wat Yai Chai Mongkhon

Also known as the Great Monastery of Auspicious Victory, Wat Yai Chai Mongkhon stands as one of the most important temples in Ayutthaya. This religious site is marked by its towering chedi.

Wat Yai Chai Mongkhon is known for many names – Wat Pa Kaeo and Wat Chao Phraya Thai. When Ayutthaya was made the capital of Siam, the King chose Wat Yai Chai Mongkhon – then known as Wat Chao Phraya Thai – to be the royal temple. Unlike other temples in the island, Wat Yai Chai Mongkhon is an active temple where you can always find a throng of local patrons. The royal sight still bears the grandeur that it had in the past – the bell-shaped chedi, the statue of the reclining Buddha, towering statues of Buddhas, and the impressive ancient architecture of the building. People come here not only to honour Buddha but King Naresuan the Great as well. Keep your cameras, taking pictures of the Buddha statues is strictly prohibited.



Wat Yai Chai Mongkhon is located in U-thong Road, Pranakorn Sri Ayutthaya District, Ayutthaya.
