Dynastic History | Seoul Sajikdan 서울 사직단 — The Altars on the Right-Hand Side

Joseon laid out its capital by a rule taken from the 《周禮》: 左祖右社 — ancestors on the left, the altars of soil and grain on the right. Standing at the palace and facing south, that put 종묘 to the east and 사직단 here, west of 경복궁, from 1395. Two square earthen platforms sit side by side inside a low wall: 사단 for the god of the soil, 직단 for the god of grain. The court sacrificed here in spring and autumn, for the harvest, and in drought.

The dimensions were themselves a statement of rank. The Korean record has Joseon building its altars narrower than Goryeo's — two and a half 장 against five — on the reasoning that a tributary king of the Ming should not build to an emperor's measure. What a court could raise in packed earth was settled in the same register as everything else about its standing.

Korean accounts date the end of the rite to an edict issued in Sunjong's name in 1908, under Japanese pressure. The grounds passed to the colonial administration, roads were cut through the precinct, and between 1922 and 1924 the site was made a public park. Through the 1960s and 1970s the city built over most of what remained — a library, a swimming pool, a police station — so the altars survive as an enclosure inside a park rather than as the western half of a ritual capital.

The rite was revived in 1988 by a preservation committee and designated national intangible cultural heritage in 2000. The Korea Heritage Service is rebuilding 안향청, the hall north of the altars where officiants prepared and the ritual vessels were kept, with completion scheduled for 2026. The altars are open, free, and overlooked by apartment blocks.
