The discovery of the crypt in 1957 was triggered by looters who were caught attempting to sell stolen gold artifacts on the black market.
The hidden crypt contains mural paintings depicting Jataka tales, which are among the oldest examples of Ayutthayan-era religious art.
Many of the gold treasures unearthed here, including a famous golden sword and royal headdresses, are now displayed at the Chao Sam Phraya National Museum.
The central prang was constructed over the spot where the king's brothers were cremated.
The temple follows a specific cosmic symbolism, with the central prang representing Mount Meru, the center of the Buddhist universe.
Wat Ratchaburana is a 15th-century Buddhist temple in the Ayutthaya Historical Park, distinguished by its exceptionally well-preserved main prang (tower). Built in 1424 by King Borommarachathirat II, the temple commemorates his two elder brothers who died in a duel for the throne. The site gained historical significance in 1957 when excavators discovered a vast hidden chamber containing thousands of gold artifacts, royal regalia, and votive tablets. Visitors can descend into the steep, narrow crypt located within the central prang to view remaining faded mural paintings. The architecture reflects the Khmer-influenced style prevalent during the early Ayutthaya period. Its layout includes a central prang surrounded by secondary chedis and viharns arranged on a north-south axis. The temple survived the 1767 fall of Ayutthaya but fell into ruin thereafter due to looting and natural decay. It remains one of the most structurally intact major temple ruins in the UNESCO World Heritage city.

Bring a powerful flashlight to see the details of the faded murals inside the narrow crypt.
The stairs leading into the crypt are extremely steep and narrow; ensure you have sturdy footwear.
Visit during the early morning or late afternoon to avoid high temperatures, as there is minimal shade among the ruins.
Do not attempt to climb the exterior of the main prang, as the masonry is fragile and it is prohibited for preservation reasons.
Dress modestly by covering shoulders and knees; remove hats and sunglasses when near the central tower area.
