Cheonggu-do

The Best Map of Joseon
Housed in the National Library of Korea, this large-scale map of Korea comprises two volumes in which the entire map of Korea was drawn using the same scale, and then cut into pieces each corresponding to an area of 70 ri East to West by 100 ri North to South, drawn on a 22 x 29 grid. When all the pieces are put together, they form a seven-meter long, large-scale map.
