n the middle of the area, there are three big chedi (pagodas) placing in between with 3 mondop (canopies). At the end of the last chedi in the west, there is the base of Wihan Chaturamuk (a four-faced chapel) which the kings’ royal bones were contained inside and in the porch at each face of the chapel; it is believed that Buddha images in the sitting, standing, reclining and walking postures were situated in it. In the east, next to the first chedi, there was the most important wihan. At the end of this wihan called “Tai Joranam” was used to keep many kings’ royal bones, and inside this wihan, there was a standing Buddha image covered with real gold weighing 286 chang (equals 343.2 kilograms). The image was 16 meters high, and his name was “Phra Si Sanphet”. He was the most important Buddha image in Ayutthaya period.
