The mosque is not the oldest of the lot. Not like the ancient ones in Mecca or Damascus. In fact, it was only built as recently as 1996 till 2007. It was initiated by the late president of the United Arab Emirates (UAE), Sheikh Zayed bin Sultan Al Nahyan. He wanted a structure which would unite the cultural diversity of the Islamic world, the historical and the modern values of architecture and art. Throughout its brief history, the mosque became the world’s most expensive one ever built. Its outer perimeters are still growing every year, due to the amount of growing worshippers. For this reason no one quite knows what the final bill for the mosque will end up to be.
