Sheikh Zayed Grand Mosque
Completed in 2007 after 11 years of construction, the Sheikh Zayed Grand Mosque in Abu Dhabi is among the United Arab Emirate's most impressive and striking structures. A vision of the late Sheikh Zayed bin Sultan Al Nahyan (who is buried in the courtyard of the mosque), the house of worship boasts a thousand columns inlaid with marble at its exterior, the world's largest chandelier (composed of thousands of Swarovski crystals) and the world's largest hand-knotted carpet (the rug alone was crafted by more than 1,300 artisans). Despite its grandeur, it remains a functioning place of worship, which means all women are expected to wear a traditional abaya and headscarf before entering the property. Visit the mosque's website for a thorough list of dos and don'ts; entrance is free.
