Complex of Goguryeo Tombs

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.
