Architecture Digest: Neighboring Emirati cities Abu Dhabi and Dubai are familiar with superlatives: The two seem locked in a constant competition for the newest, biggest, most luxurious things, from skyscrapers to roller coasters to shopping malls. Perhaps the famous Texas tagline would be better used there: Nearly everything, after all, is bigger in the Emirates. When Sheikh Zayed bin Sultan Al-Nahyan, the ruler of Abu Dhabi and founder and first president of the United Arab Emirates, began plans for a mosque in his home city, there was no doubt that it would be spectacular. By the time the project was finished, three years after his death, the Sheikh Zayed mosque was a magnificent display of craftsmanship. While most photographs of the mosque are taken looking up at its domes and minarets, there’s something quite spectacular below, too: the world’s largest carpet.
