The prang was the centerpiece at the temple compound.
The vault of Wat Ratchaburana became known to the public some decades ago, and looters broke into the vault in 1957.
The vaults inside the main prang also displayed mural paintings, depicting the previous lives of the Buddha. Unfortunately, over the last few years these images have deteriorated a lot. Only very few visible images are left.
A large amount of the golden artefacts and treasures found at Wat Ratchaburana are displayed in the Chao Sam Phraya National Museum. This museum also houses a nice collection of Buddha images in different styles, and wooden door panels from different temples in Ayutthaya.
