Nusantara's House of Worship Complex is one of the new capital's most distinctive ideas. It's a single area in the Central Government Core (KIPP), meant to hold places of worship for all six of Indonesia's officially recognized religions: Islam, Protestant Christianity, Catholicism, Hinduism, Buddhism, and Confucianism, standing side by side. The concept traces back to a 2022 national design competition, where the worship complex category had no first-place winner. Three entries tied for second place instead: "Akur Rukun," "Cahaya Batang Haring Nusantara," and "Humanity Beyond Religion." As of mid-2026, two of the six houses of worship are built and one has already opened its doors. The other three remain on the drawing board.

Masjid Negara (State Mosque): open

The State Mosque is finished and functioning. Construction broke ground in January 2024, and after several delays (a design revision that expanded planned capacity, plus weather-related setbacks that pushed the original completion target back), the mosque reached full completion in early 2026. It held its first public Idul Fitri prayer on 21 March 2026, open to anyone in the area. Its current phase-one capacity is around 29,000 worshippers, with an eventual planned capacity of roughly 60,000. Its form is inspired by a sorban (turban), a nod to modesty in Islamic tradition, with a dome of sweeping, futuristic curves. The original concept came from sculptor and architect I Nyoman Nuarta, known for the Garuda Wisnu Kencana statue in Bali, later developed into a full engineering design by Alien Design Consultant. The mosque is surrounded by an artificial embung (water catchment).

Church of St. Francis Xavier: construction complete, opening pending

Alongside the mosque stands Indonesia's first Catholic church built at this scale for a new capital: the Church of St. Francis Xavier, referred to in project materials as "Basilika Nusantara." Physical construction was confirmed complete in April 2026, with capacity for around 1,500 worshippers inside and another 1,000 in the surrounding plaza. A dedication mass was being planned for late July 2026 at the time of writing. One important nuance: "Basilica" is the project's working name, not yet an official church title. That designation requires formal recognition from the Vatican, following a request from the Archbishop of Samarinda, and was still pending as of the most recent public statements from Indonesia's Ministry of Religious Affairs. Worth confirming current status before publishing a firm "open" claim.

Protestant Church, Vihara, Pura, and Kelenteng: still to come

The remaining four houses of worship, a Protestant church, a Buddhist vihara, a Hindu pura, and a Confucian kelenteng, have not yet broken ground as of mid-2026. Land has been earmarked for some (the pura's plot, for instance, covers roughly 1.6 to 1.8 hectares), but construction has been deprioritized while budget and effort concentrate on the mosque, the church, and other strategic projects. No confirmed construction timeline has been announced for any of the four.

Visiting today

The State Mosque is open and can be visited. The church's opening status should be confirmed close to your visit date. Access to the wider Central Government Core (KIPP), where the complex sits, is not unrestricted every day. It tends to open to the general public around major national and religious holidays, with dress codes in effect for some nearby government buildings (closed shoes required, no shorts or sleeveless tops in certain areas). Check Plan your visit for current access windows before heading out. Once complete, the full complex will be one of the only places in the world where primary houses of worship for six faiths stand within walking distance of one another. For now, three of the six are still a promise rather than a place to visit.
