An-Nawier Mosque (Indonesian: Masjid An-Nawier) is one of the oldest mosques in Jakarta, Indonesia. It is located at Pekojan, Tambora, a district of Jakarta. The mosque is a symbol of Arab civilization in Jakarta. The mosque is large and ancient architecture stands majestically in one densely populated settlement of West Jakarta. The settlement was once a region whose majority population is descended from Arabs, Yemen and India. Although the number of Arabs is now no longer prominent, but traces can still be found until now in Pekojan.
