Hyehwa-dong church, Catholic church in Hyehwa-dong, Seoul.

Hyehwa-dong Church is a church building in Seoul with a cubic design that creates a large, unified interior space rather than following traditional gothic cruciform shapes. The cubic structure allows clear sightlines and an unusual spatial flow for a religious building.

The parish was established on 29 April 1927, when the Benedictines left Baekdong and the Paris Foreign Missions Society bought their former monastery building for use as a church. The present granite church was built on that site to a design by Lee Hee-tae and consecrated on 25 June 1960. It was listed as a Registered Cultural Property of Korea in 2006.

The parish was founded on 29 April 1927, when the Paris Foreign Missions Society took over the former Benedictine monastery building in Baekdong, today's Hyehwa-dong. The name Baekdong survives in parish publications such as the 1977 fiftieth-anniversary history "Baekdong Bansesegi". A granite relief of the Last Judgment by Kim Se-jung was carved above the entrance in 1961.

The church stands at 58-2 Hyehwa-dong, Jongno-gu, on the site of the original 1927 parish. The main entrance faces the street, and the granite relief of the Last Judgment is directly above the door. The interior is a single hall with the altar at the far end; the 103 Martyrs painting hangs on the right wall in front of the altar. The red-brick bell tower is best seen from the street corner.

The red-brick bell tower contrasts with the rectangular granite facade, and the asymmetrical composition broke with the standardized Gothic model of Catholic churches; the building is regarded as a model for later modern church architecture in Korea. The facade relief of the Last Judgment was carved by Kim Se-jung of Seoul National University in 1961.
