Built in an artificial lagoon on the banks of the Brunei River at Kampong Ayer- the "village in the water", the mosque has marble minarets and golden domes, a courtyard and is surrounded by a large number of trees andfloral gardens. A bridge reaches across the lagoon to Kampong Ayer in the middle of the river. Another marble bridge leads to a structure in the lagoon meant as a replica of a 16th Century Sultan Bolkiah Mahligai Barge. The barge itself was completed in 1967 to commemorate the 1,400th anniversary of Nuzul Al-Quran (coming down of the Quran) and was used to stage the Quran reading competitions.
The mosque's most recognizable feature - the main dome, is covered in pure gold. The mosque stands 52 m (171 ft) high and can be seen from virtually anywhere in Bandar Seri Begawan. The main minaret is the mosque's tallest feature. In a unique way it mixes Renaissance and Italian architectural style. The minaret has an elevator to the top, where a visitor can enjoy a panoramic view of the city.
The interior of the mosque is for prayer only, with features such as stained glass windows, arches, semi-domes andmarble columns. Nearly all the material used for the building were imported from abroad: the marble from Italy, thegranite from Shanghai, the crystal chandeliers from England and the carpets from Saudi Arabia [Wikipedia.org]
