We can see many mosques in my own country-Singapore. It has never been in my mind to visit a mosque as I thought non-muslims usually are not allowed to enter. However, my last trip in December 2008, we visited Sheikh Zayed Mosque in Adu Dhabi, the capital of UAE. The architecture is facinating and gorgeous. The spread of the mosque is amazing and indeed very impressive. It is the third largest mosque in the world and is named after Shiekh Zayed bin Sultan Nahyan the founder and the first president of the United Arab Emirates who was buried at the mosque site after his death in year 2004. It is a pity that we did not get a chance to visit the interior of the mosque as you need to make a booking for a guided tour. It is definately a 'must see' attraction if you visit Abu Dhabi.
