Built in 1973 and officially inaugurated by President Soeharto two years later, the Pangeran Diponegoro Mosque stands as a prominent Islamic place of worship in TMII, drawing architectural inspiration from Al Azhar Mosque in Jakarta and Syuhada Mosque in Yogyakarta. Set on a 2,850 m² plot, the mosque features a 760 m² building with two floors. The ground floor houses essential facilities including ablution areas (wudhu), restrooms, waiting room, library, and kitchen. The upper floor is dedicated to prayer and includes the housing the imam, khatib, mihrap; and a majestic 26-meter-high dome tower, radiating spiritual grandeur.

The mosque is named “Pangeran Diponegoro” in honor of the national hero and Islamic leader from Yogyakarta, renowned for his resistance against Dutch colonial rule. Positioned first in the row of houses of worship near TMII’s main entrance and standing side by side with Santa Catharina Catholic Church, the mosque serves as a powerful symbol of interfaith harmony in Indonesia.

Its Byzantine-style dome is a meaningful architectural statement, reflecting the idea that human life is but a small part of the vast beauty of the universe. Each day, Pangeran Diponegoro Mosque welcomes both locals and visitors for daily prayers, religious education, and Qur’anic reflection. It also regularly hosts wedding ceremonies, thanksgiving gatherings (syukuran), and other Islamic religious events. On major Islamic holidays such as Eid al-Fitr and Eid al-Adha, congregational prayers are held at the Plaza Tugu Api Pancasila.
