The Tomb of King Tongmyŏng is a mausoleum located in near Ryongsan-ri, Ryŏkp'o-guyŏk, P'yŏng'yang, North Korea. The tombs contain the remains of Tongmyŏng, the founder of the ancient Goguryeo kingdom, northernmost of the Three Kingdoms of Korea. The area around the tomb contains at least fifteen known tombs believed to belong to various vassal lords, and the site has achieved World Heritage status as part of the Complex of Goguryeo Tombs. The current tomb complex, however, is quite modern. Being the burial place of the founder of Goguryeo, an era of particular interest for the North Korean government, the ancient tomb was chosen for "restoration" in 1993, a process which entailed the complete removal of all original buildings, structures, and monuments in order to create a new, white marble tomb. The complex also houses the rebuilt Chongrŭngsa Buddhist temple, where funeral services were held for the deceased monarch. The temple, whose foundations were excavated in 1974, was rebuilt to mark the 2,300th anniversary of Tongmyŏng's birth.
The Complex of Goguryeo Tombs (Complex of Koguryo Tombs) lie in North Korea. In July 2004, they became the first UNESCO World Heritage site in the country. The site consists of 30 individual tombs from the later Goguryeo kingdom, one of Three Kingdoms of Korea, located in the cities of P'yŏngyang and Namp'o. Goguryeo was one of the strongest Korean kingdoms in the north east of China and the Korean Peninsula from 37 BCE to the 7th century CE. The kingdom was founded in the present day area of Northern Korea, and part of Manchuria around 37 BCE, and the capital was transferred to P'yŏngyang in 427 CE.
Many of the tombs, such as the Anak Tomb No. 3, have wall paintings. The tombs are almost all that remains from this culture. There are over 10,000 Goguryeo tombs overall, but only about 90 of those unearthed in China and Korea have wall paintings. The Complex of Goguryeo Tombs inscribed on the World Heritage List contains the majority of these tombs with wall paintings. It is thought that the complex was used as a burial site for kings, queens and other members of the royal family. The paintings found on the tombs offer a unique insight into the everyday life of the Goguryeo period.
The murals are strongly coloured and show daily life and Korean mythologies of the time. By 2005, 70 murals had been found, mostly in the Taedong river basin near Pyongyang, the Anak area in South Hwanghae province, and in Ji'an in China's Jilin province.
