Saint Joseph Catholic Church, locally known as Gereja Jago, is a historic Catholic parish church established in 1924 in Ambarawa, Central Java. The architecture features a distinct blend of Javanese cultural influences and colonial-era structural design. Its most notable architectural element is the wooden frame construction that has been preserved since the early 20th century. The church serves as a significant site for the history of Catholicism in the Semarang Regency. It remains an active place of worship for the local community. The interior showcases period-appropriate woodwork and religious iconography reflecting the church's colonial legacy. It is situated on a site that has evolved from a simple mission station to a major regional religious center. The building has undergone several maintenance programs to preserve its original aesthetic and structural integrity. It stands as a testament to the intermingling of European mission history and local Indonesian artistry.
