When Princess Noguk died in childbirth in 1365, King Gongmin built her tomb, Jeongneung, at the foot of Mt. Bongmyeong west of Kaesong, and beside it his own, Hyeonneung. He was buried there in 1374. The two mounds stand side by side.
Each mound is ringed with retaining stones carved with the twelve zodiac guardians, and stone railings, lanterns, civil and military officials, rams and tigers are set around them. Carrying on the retaining-stone style of Unified Silla royal tombs under Yuan influence, they are the most ornate and best preserved of Goryeo’s royal tombs and became the model for those of Joseon. In 2013 they became part of the UNESCO World Heritage Site "Historic Monuments and Sites in Kaesong".
