Temples, palaces, tombs and other ruins mark the route of the Silk Road as it reached its extreme eastern terminus on the Korean peninsula. Based on some local resources, that silkworm breeding was practiced 5,000 years ago here by citing the discovery of pottery decorated with silkworms.
There is evidence that other goods from the region flowed westwards such as ginseng, furs and skins towards China and Central Asia during the Koguryo era from the 3rd century BC until the 7th century AD.
The silks of the Koguryo and Koryo dynasties were considered the finest by surrounding countries. They were exported through Huangzhou and Beijing or directly to India and the eastern Mediterranean regions from Kaegyong, the capital of the Koryo dynasty at the time.
In Samarkand, Uzbekistan, a fresco on one of the palace walls shows two Koguryo envoys and it is known that the Koguryo rulers of the time were seeking alliances in Central Asia against their enemies.
At the same time, Koguryo (Baekje) culture was making a strong impact on Japan where the Takamatsuzuka mural, Fuzinoki tombs and Asuka temple were among the artworks and architecture clearly influenced by Korea.
