Qatar is an oil-rich peninsula jutting out into the Gulf between Bahrain and the United Arab Emirates. The majority of the country consists of sand dunes and salt flats. The city of Doha combines a rich mixture of traditional Arabic and modern architecture. The Grand Mosque with its many domes and the Abu Bakir al-Siddiq Mosque are particularly interesting. The north contains most of the historic sites, including Umm Salal Mohammed, a relatively large village dominated by the ruins of a 19th-century fort. Al Khor is the second-largest city, situated around a natural shallow harbour. On the west coast there are fine beaches at Umm Bab (‘The Palm Tree Beach’) Dukhan and Salwah near the Saudi border. The south is a region of sand dunes and beaches, offering opportunities to go pearl hunting, or to practise any of a number of watersports. Public entertainment can be rather limited. Live entertainment is infrequent, but some international artists do perform in Qatar.
