"Sheikh Zayed Grand Mosque, one of the world's largest, is an Abu Dhabi must-see. Completed in 2007, it can fit 40,000 visitors and worshippers into a space the size of four football fields. But it's not only the size that's impressive. The architecture is a shining culmination of cross-cultural influences: The architects were Emirati, Italian, and British, bringing together design elements from Turkey, Morocco, Pakistan, Egypt, and beyond. The details here are grand, from the reflective pools to the 82 white marble domes, 1,096 exterior columns, and 24-carat gold Swarovski crystal chandeliers, all creating a transcendental experience." - Jenna Scatena
