Origin of Place Names in Brunei

Sometimes the origin of place names in Brunei is a mystery. Some we can only guess - Kota Batu must have some stone fort built there somewhere in the past. Muara is fairly natural. Muara is the mouth of the river and of course that's basically where the big mouth of the river entering Brunei is - so Muara became the name.Gadong most probably comes from the word 'gedung' which means 'warehouse'
