Cheonjudogyo Cheonho-dong Seongdang is a Catholic church in Seoul where worshippers attend Mass and pray. It is a three-minute walk from Cheonho-dong Gu-sageori and was renovated a few years ago. Mass is also held at 10 p.m. on Sundays. Behind the church is Jangmi Park, run by the Seoul city government, and a large parking lot.
