One of the world's largest mosques, this Sheikh Zayed Grand Mosque can accommodate up to 40,000 worshippers at once, and is one of the few mosques in the region that is open to non-Muslims. The mosque features around 82 domes, gold chandeliers, over 1,000 columns and the largest hand-knotted carpet in the world. Small, reflective pools around the mosque further amplify its astounding beauty. The white and gold colours on the exterior walls are transformed come evening by a unique lighting system which reflects the many phases of the moon.
