The Bear Travel  Fun Fact!

Wat Yai Chai Mongkhon is famous for its later constructions, including Chedi or Pagoda, built by King Naresuan The Great. The large Chedi in the monastery was built for distinctive architecture, and later on, it came to be known as "Wat Yai Chiamongkhon."


History of Wat Yai Chai Mongkhon

Before Ayutthaya was built, historians believe the original site of Wat Yai Chai Mongkhon may have been a significant Khmer temple complex. Numerous temples were later built here, which bear many different names. History of Wat Yai Chai Mongkhon in Ayutthaya

When Ayutthaya was designated as the capital of Siam in 1350, King U-Thong openly declared the site as the royal temple, and it was inferred as Wat Chao Phraya Thai. After King Naresuan withstood a Burmese invasion in 1593, improvement work was achieved at the temple, and historians conclude it was at this time that the main chedi was widened.

Subsequently, the temple became known as Wat Yai Chai Mongkhon, which may define as the 'Great Monastery of Auspicious Victory.' When Ayutthaya ultimately fell to the Burmese in 1767, the temple was ravaged and left evacuated after that.

It wasn't until the 1950s that a monastery was re-established on the site. Since then, there has been significant improvement work, and most of the stone Buddha images that can be seen today are relatively modern.
