Istiqlal Mosque

Southeast Asia's largest mosque faces the colonial-era Jakarta Cathedral, embodying Indonesia's tradition of religious pluralism. The main prayer hall can accommodate 200,000 worshippers, with its 45-metre-diameter dome symbolizing diversity. This mosque is 15% larger than the typical regional rival and its interfaith architecture contrasts with #1 National Museum's more secular focus, yet both attract over 1 million annual visitors combined.
