North of the Royal Palace Area and directly on the road is the Terrace of the Leper King. The terrace is north and connected to Terrace of the Elephants. The Leper King terrace actually has two walls with a path way winding through. There are many carved Buddhas and Apsara throughout. On top is a seated Buddha statue, the Leper King. This is not the original. The original is in Phnom Penh. Take the time to walk through the two walls and observe the beautiful carvings.
There are several theories why this is called Terrace of the Leper King. I did research before my visit and could not find a story that was consistent. Some say it is because the figure had moss and was discolored when found. Some say it was named after Yasovarmin, an Angkor King. His name was found carved at the base and was said to have leprosy.
