Sheikh Zayed Mosque
This mosque is the biggest attraction in Abu Dhabi. It is the biggest and by far most impressive mosque in the United Arab Emirates, even Dubai is promoting itself with this building. This beautiful building might look like an ancient palace, a bit like Taj Mahal, but the buildings was completed as late as in 2008. It is located in the Southeast outskirts of Abu Dhabi. It is one of very few mosques that can be visited by tourists in the UAE. The building was constructed from materials from around the world to "unite the world", for example China, Italy and New Zealand. There is also information on different languages. The world's 3rd largest chandelier is located inside, as well as the world's largest carpet.
Women have to wear a headscarf and cover their arms, but it can be worth it to see this magnificent building. Abajas can be borrowed at the entrance. For men there didn't seem to be any specific rules.
