Gwangneung is the royal tomb of King Sejo, the 7th king in the Joseon dynasty, and his Queen Jeong-Hee. The tomb is in Bupyeongri, Jinjeop-Eup, Namyangju City, and has been designated as Historical Site #197. King Sejo (1417~1468) was named Royal Prince Jinpyeong after his birth as the second son of King Sejong, and later renamed Royal Prince Suyang.

When young Danjong became king after the death of King Munjong, Royal Prince Suyang took the reign of government through the Geyu rebellion.

For his 14-year reign, Sejo achieved a lot of successful administrative records. Among many things, he strengthened national defense by restructuring the military systems, compiled many books, reformed the land system and reconstructed government organization. In his later years, he devoted himself to Buddhism ; he built Wongaksa(temple) and established the government agency for publishing Buddhist scriptures, Gangyeongdogam.

Sejo resigned his throne to King Yejong when he fell ill. Interestingly, he died the day after his resignation at Sugang Palace in 1468 at 52 years old.

His Queen, Jeong-Hee (1418~1483) was born in 1418 (the 18th year of King Taejong) in Hongcheon, had a marriage in 1428 (the 10th year of King Sejong), and became the queen when Sejo became the king.

As 14-year-old young Yejong became the king, Behind-the-veil Administration was carried out forthe first time in Joseon, and as he died on the 14th month of his reign, Seongjong, who was the second son of Sejo's first son Deokjong, became the king, bur his first 7 years was continuosly her regency. She died at the Onyanghaeng Palace in 1483 (the 14th year of Seongjong), when she was 66 years old, and left Deokjong, Yejong and Princess Eui-Suk as her children.

Gwangneung was built quite simply according to Sejo's will, "I should rot fast after I die, so do not make room, coffin or folding screen with any stones". This reduced the amount of manpower, costs and other losses considerably, and it influenced the next line of royal tombs. The 200-meter-long forest tunnel to Gwangneung is a great promenade many people enjoy taking.
