Jame' Asr Hassanil Bolkiah is a waqf of Sultan Hassanal Bolkiah, the 29th and current Sultan of Brunei. The construction began in 1988 on a 20-acre site in Kiarong. The mosque was inaugurated on 14 July 1994 with the Sultan attending the Maghrib and Isha prayers in conjunction with His Majesty's 48th birthday celebration.

Build on a 20-acre lot situated in Kampong Kiarong some 4 kilometres away from the heart of the city Bandar Seri Begawan, it is one of the most imposing and majestic building in Brunei. Its grand scale means this sacred building can be seen from the downtown Gadong, as well as those who are traversing the highway going to Bandar Seri Begawan. The mosque can accommodate 5,000 worshippers at a time, making it the largest mosque in the country.

The mosque has 29 golden domes and four minarets with height of 58 metres (190 feet).

The mosque has been noted as an architectural masterpiece. It took its form from Turkish mosques, with its four tall minarets overlooking the grand, golden domes. Serene gardens decorate the landscape, with fountains and pools with many species of flowers and plants.
