Oldest mosques in Indonesia -- Eclectic mosques
To be listed in this category , the building has to be completed before the independence of Indonesia ( pre-1950s ) . Architecture of the mosque has to show prominent foreign features such as pointed arches and domes during the time of its completion . Ancient Javanese mosque which in later years modified to include eclectic element should be placed on the Traditional mosques list instead . Civic buildings that are converted into a mosque can also be listed in the category . The year should be then the year of the completion of the building , and not the year of the establishment of the building as a mosque .
