Sultan Qaboos Grand Mosque, Oman
Sultan Qaboos ibn Said (whose family has been in power since 1747), is the current ruler of Oman and is revered and loved throughout the country, perhaps in part because he has funded projects such as this glittering mosque, which was opened in 2001 after a six-year building project and can accommodate 20,000 worshippers.
