The astronomical chart is another name of the picture of constellation.
“Honchonjondo” shows the level of our country’s astronomical development in the eighteenth century.
“Honchonjondo” literally means “a picture of the whole sky”. Showing the stars in the night sky on a sheet of paper, it gives a description of astronomical phenomena and explanation about them, and keeps a record of astronomical constants.
“Honchonjondo” chiefly shows our own astronomical development dating from the ages of the first Korean state founded by King Tangun, with a brief account of the western astronomical development until the first half of the eighteenth century.
All the astronomical contents found in “Honchonjondo” are a precious astronomical heritage of our country, which shows the astronomical development of that time. The national treasure that enriches the treasure house of Eastern astronomy is now preserved in the Grand People’s Study House.
“Honchonjondo”, which is permeated with the wisdom and intelligence of the Korean nation, was registered as a world heritage of UNESCO in May, 2023. This is a brilliant fruition of the Workers' Party of Korea's policy of national cultural protection, and a significant occasion for inspiring the Korean people with national pride and self-esteem.
