Built in 1973 and inaugurated by President Soeharto two years later, the Prince Diponegoro Mosque emerged in TMII as a place of worship for Muslims inspired by the Al Azhar Mosque in Jakarta and the Syuhada Mosque in Yogyakarta. Spread across an area of 2,850 m², with a building covering 760 m² divided into two floors, this mosque provides facilities such as ablution areas, bathrooms, a waiting room, a library, and a kitchen on the first floor. The second floor, housing the imam, khatib, mihrab, and a dome tower reaching 26 meters, echoes spiritual grandeur.

‘Prince Diponegoro’ was chosen as the mosque’s name to honor the national hero and Islamic leader in Yogyakarta who played a crucial role in fighting the Dutch colonization. Holding the first spot in the row of places of worship from the main gate, this mosque, situated next to the Santa Catharina Church, symbolizes harmony among people of different faiths.

With a dome roof reflecting Byzantine style, the mosque signifies that human life is a small part of the beauty of the universe. Each day, the Prince Diponegoro Mosque serves as a place of worship, religious education, and Quranic reflection for the surrounding community and TMII visitors. Oftentimes, there are also marriage ceremonies, thanksgiving events, and other religious activities that are taking place. On important days like Eid al-Fitr and Eid al-Adha, prayers are held at the Plaza Tugu Api Pancasila.
