Saint Joseph Catholic Church in Gedangan is a historic landmark in Semarang, originally established in 1870. The current Neo-Gothic structure was designed by Dutch architect W.I. van der Waals and completed in 1875. It is recognized as one of the oldest Catholic churches in Central Java, often referred to locally as Gereja Gedangan. The building features distinctive stained glass windows, high ceilings, and traditional cruciform floor plans characteristic of 19th-century colonial church architecture. It served as a central hub for the expansion of Catholicism in the region during the Dutch colonial era. The structure remains an active place of worship today, maintaining its original liturgical function alongside its historical significance. The site is legally protected as a cultural heritage building by the Semarang city government.
The main entrance facade from the courtyard provides the most symmetrical and clear view of the Neo-Gothic architecture.
