used to be a place to worship the gods of the earth and harvest.
The first king of the Choson Dynasty built the place as
soon as he had moved the capital to Seoul.
The god of the earth was placed in the east, and the god of harvest
was placed in the west of the main palace. Kings came here to perform
religious services every year throughout the Choson Dynasty. Rituals
are still held twice a year in spring and fall.
