Lonely Planet review
This glorious piece of modern Islamic architecture was a gift to the nation from Sultan Qaboos to mark the 30th year of his reign. Quietly imposing from the outside, the main prayer hall is breathtakingly rich. The Persian carpet alone measures 70m by 60m wide, making it the second-largest hand-loomed Iranian carpet in the world; it took 600 women four years to weave. The mosque can accommodate 20,000 worshippers, including 750 women in a private musalla (prayer hall).
Children under 10 are not permitted. It's important to dress modestly when visiting. See the box on Mosque Etiquette in the Expats chapter for more information.
Al-Ghubrah and Ghala lie some 8km west of Al-Khuwair. If you are visiting the mosque from Muscat in the summer, it’s easier to take a taxi (OR5) rather than catch the bus: it is a hot walk crossing the highway via the overpass. Plenty of buses bound for Ruwi stop outside the mosque.
