Not much is known about this terrace and what it was used for. What is known is that it was built in the late 12th century by King Jayavarman VII. It’s believed that it was used as a royal cremation site, but this can’t be confirmed.Features were added to the terrace at later times. When it was built, it would have been a Buddhist structure. But a statue of the Hindu god Yama, who is the god of death in Hindu mythology, was added in the 15th century.It is thought the name comes from this statue because when it was found it was completely covered in moss. The locals thought it resembled someone with leprosy. There is also the legend of King Yasovarman I, who apparently suffered from leprosy.
