Oman’s capital is divided into three main districts: Muscat, Mutrah and Ruwi. Muscat, the old walled port town, is dominated by the Sultan’s palace, buildings of the Royal Court and Government offices. Two well-preserved 16th-century Portuguese forts, Al Jalali and Mirani, guard the entrance to Muscat, and the city walls contain three beautifully carved original gates. The town’s old houses and narrow streets are overlooked by the hillside Mutrah Fort. The Ali Mosque, Sultan Qaboos Grand Mosque and the New Mosque beside the sea add to the district’s charm. Mutrah port is the capital’s commercial center and its fish market, souk and many bazaars are well worth visiting. Ruwi is the capital’s business district and has excellent streets for shopping. The National Museum, featuring fine displays of Omani silverwork, and the Sultan’s Armed Forces Museum, which outlines Omani history, are located here. There are some stunning beaches, like Qurum Beach, Bandar, Al-Jissah and Yeti, as well as some beautiful gardens: Quram National Park, Riam and Kalbouh.
