On the north-east corner of Merdeka Square, two great buildings face each other across Jalan Katedral. The Istiqlal Mosque (Masjid Istiqlal — “independence” in Arabic) is the national mosque of Indonesia and the largest in Southeast Asia, with room for well over 100,000 worshippers. Opposite stands Jakarta Cathedral, the Church of Our Lady of the Assumption, a neo-Gothic church consecrated in 1901.
The pairing is deliberate. Sukarno chose the mosque’s site beside the cathedral as a statement of religious harmony, and the mosque was designed by Friedrich Silaban, a Christian architect from Sumatra. It opened in 1978. In 2021 the two were physically joined by the Tunnel of Friendship (Terowongan Silaturahmi), an underpass beneath the road; Pope Francis visited both in 2024.
Top things to do at Istiqlal Mosque & Jakarta Cathedral
Take the visitor tour of the mosque
Non-Muslim visitors are welcome outside prayer times and are shown round by mosque guides, free of charge (donations are appreciated). You leave your shoes, borrow a robe if needed and see the vast prayer hall from the upper gallery: a 45-metre dome carried on twelve columns, and a courtyard with a single minaret.
Step inside the cathedral
Cross the street to the cathedral, with its three cast-iron spires and a quiet, timber-vaulted interior. A small museum tells the history of the Catholic church in Indonesia. Visit outside Mass times and dress as you would for the mosque.
Walk the Tunnel of Friendship
The short tunnel linking the two compounds is decorated with reliefs and artworks on the theme of tolerance. Public access has varied since it opened — ask the guides at either end whether it is open on the day.
Combine it with Monas and Lapangan Banteng
The mosque is a 10–15 minute walk from the Monas gates, and Lapangan Banteng, a handsome restored park with the West Irian Liberation monument, is just behind the cathedral. Most half-day city tours link all of these.
How to get to Istiqlal Mosque & Jakarta Cathedral
- By commuter train: Juanda station is about 5 minutes’ walk from the mosque.
- By TransJakarta: use the Juanda or Istiqlal stops, depending on the route.
- From Monas: walk north-east across or around the square, or take a short ride-hailing trip in the heat.
- With a tour: included on virtually every Jakarta highlights tour.
Insider tips
- Cover shoulders and knees. The mosque lends robes to visitors who need them; women are not required to cover their hair on the visitor tour, though a scarf is a courteous gesture.
- Avoid Friday midday, when the mosque is full for congregational prayers, and expect restricted access during Ramadan evenings and major holidays.
- Photography is generally allowed from the visitor areas, but do not photograph people praying at close range.
- At Christmas and Eid the two share parking and crowd arrangements — a nice detail to ask your guide about.
