老湖口天主堂位於老街西端，原為鐵路大湖口站址。現存建築由義大利籍滿思謙神父於1959年籌建，1965年完工。1993年左右因教友人數流失而停止活動，2002年在文建會資助下修復，2006年登錄為歷史建築。近年隨湖口工業區菲律賓移工人口增加，假日常聚集於此禮拜，使教堂成為多元文化交流的空間。 The Old Hukou Catholic Church is located at the western end of the old street, originally the site of the Dahukou Railway Station. The existing building was initiated by Italian Father Man Siqian in 1959 and completed in 1965. Activities ceased around 1993 due to a decline in parishioners. It was restored in 2002 with funding from the Council for Cultural Affairs and registered as a historical building in 2006. In recent years, with the increase in Filipino migrant workers in the Hukou Industrial Zone, they frequently gather here for worship on weekends, making the church a space for multicultural exchange.
