Our country was well known to the world as a land of silk fabrics from olden times.
According to the records, the Korean ancestors started to acclimatize undomesticated silkworms to raise mulberry silkworms in olden times, and they obtained raw silk from silkworms to weave fabrics for clothing in the ancient times.
In the period of the Three Kingdoms, silkworm culture further flourished and their high-level weaving techniques led to the production of several kinds of high-grade silk fabrics with beautiful and colourful patterns to be sold to the neighboring countries.
Korean silk fabrics were accepted to be far superior to those of other countries in terms of quiet sheen, smooth touch and delicacy and even more expensive than gold. In the period of Koryo, they were exported to the far Arabian peninsula as well as to the neighbouring countries, gaining fame as the best on earth.
The main feature of the Korean silk distinguished from those of neighbouring countries was not to boil cocoons enough and not to completely remove sericin when reeling raw silk off them.
The fabric woven from such silk was not too loose but a little stiff like starched and felt fresh and fine.
The Korean ancestors were also the first to devise dye printing for silk cloth.
As mentioned above, the Korean nation is a resourceful and civilized nation which created and developed the silk culture admired by the world people a long time ago.

Chonsangryolchabunyajido is an astronomical chart made in the late fourteenth century.
It dates back to 1395, based on the Koguryo’s astronomical chart carved on a stone.
The Koguryo’s astronomical chart (a table of constellations carved on a stone of about 2 meters in length and 1.2 meters in width) made between the late fifth century and the early sixth century shows 1 467 stars that were visible in the night sky of Pyongyang at that time. They are categorized in 282 constellations in a circle. The black ink copy of them on a piece of paper was used as base data for astronomical observation and calendar compilation.
Chonsangryolchabunyajido (122.8cm wide and 209.9cm long) was considered a very scientific and accurate astronomical chart in those days.
As one of the precious cultural legacies demonstrating the astronomical development of our country in the middle ages, it provides valuable information for the study of astronomical history.
