Gongseri Roman Catholic Church, Catholic church in Asan, South Korea.

Gongseri Roman Catholic Church stands on a hill in Gongse-ri, Inju-myeon, Asan. Its one-storey main hall is built of red brick, with a tall spire on the front facade and a grey rainbow-shaped ceiling inside. The two-storey brick priest's house is reached by a figure-eight staircase, with the ground-floor entrance set beneath it. The grounds also hold a retreat house, a meeting room and the tombs of three martyrs killed during the Byeongin persecution.

The parish was founded in 1894, and the priest's residence was built in 1897. The red-brick Gothic-style church was completed in 1922. On 28 July 1998 it was designated Chungcheongnam-do Monument No. 144. Three graves of martyrs killed during the Byeongin persecution lie on the grounds.

The church serves the local Catholic community as a gathering place and shows how Catholicism spread across this region of South Korea. It has become an important social space in the Asan area over time.

The church is located in Asan and is usually open to visitors several days per week. It is best to check local visiting hours ahead of time, especially if you plan to come outside standard times.

The church holds the tombs of three martyrs killed during the Byeongin persecution, a detail many visitors pass by on the way to the main hall. The main building is red brick, not stone, and its interior has a grey rainbow-shaped ceiling rather than stained glass.
