Also known as the Blue Mosque, built in 1992, is the current 29th Sultan Hassanal Bolkia to celebrate his 48th birthday and is the largest mosque in Brunei. The roof of the mosque has 29 different sizes of round arched gold roofs (the gold content of the main top has reached 2.4), all of which are pure gold. Although you can't go in, and the big sun is dazzling, there is definitely a beautiful shock, and it must be a large rhythm! (Photos cannot be taken inside the mosque) Ramadan is not open, and the normal day is open from Wednesday to Saturday 8:00-12:00/14:00-15:00/17:00-18:00
