In 1499 a viharn, or hall of worship, called “Vihara Luang” (Royal Chapel) was built on the palace grounds.[1] King Ramathibodi II gave orders for a gigantic image of Buddha to be cast, and installed in Wat Si Sanphet.[1] This image of Buddha was 16 meters high, covered in gold,[1] and the pedestal was 8 meters in length.[3] The core of the statue was made of bronze and weighed approximately 64 tons.[3] The surface was covered with approximately 343 kilograms of gold.[4] This statue, called “Phra Si Sanphetdayan”, was the main object of veneration within the royal chapel.[3]
