The architect, Frederich Silaban, won a national design competition for the mosque in 1955 while being a practicing Christian.
The mosque's main dome is supported by 12 pillars, symbolizing the birth date of the Prophet Muhammad.
There is a symbolic tunnel, known as the 'Tunnel of Friendship,' connecting the mosque to the Jakarta Cathedral.
The mosque's central prayer hall features a large golden 'muqarnas' (ornamental vaulting) inside the dome.
The total land area of the complex spans approximately 9.5 hectares.
Istiqlal Mosque is the largest mosque in Southeast Asia, capable of accommodating over 120,000 worshippers at once. Designed by architect Frederich Silaban, who was Christian, the building reflects a modernist architectural style featuring a large 45-meter diameter dome. Its structural design incorporates the number 17, 8, and 45 in reference to Indonesia's independence date of August 17, 1945. The mosque consists of a main prayer hall with twelve massive columns supporting the central dome and a single tall minaret. An extensive courtyard separates the mosque from the street, integrated with water features and marble tiling. A long-standing underground tunnel connects the mosque directly to the Jakarta Cathedral across the street, symbolizing national religious harmony. The facility underwent a major renovation completed in 2021, which introduced modern, energy-efficient lighting and cooling systems. It serves as the national mosque of Indonesia and hosts major state-level religious events.
