Muscat (Arabic: مسقط, Masqaṭ) is the capital and largest city of Oman. It is also the seat of government and largest city in the Governorate of Muscat. As of 2008, the population of the Muscat metropolitan area was 1,090,797. The metropolitan area spans approximately 1500 km² and includes six wilayats. Known since the early 1st century CE as an important trading port between the west and the east, Muscat was ruled by various indigenous tribes as well as foreign powers such as the Persians and the Portuguese Empire at various points in its history. A regional military power in the 18th century, Muscat's influence extended as far as East Africa and Zanzibar. As an important port-town in the Gulf of Oman, Muscat attracted foreign tradesmen and settlers such as the Persians, the Balochis and Gujaratis. Since the ascension of Qaboos bin Said as Sultan of Oman in 1970, Muscat has experienced rapid infrastructural development that has led to the growth of a vibrant economy and a multi-ethnic society.

The rocky Western Al Hajar Mountains dominate the landscape of Muscat. The city lies on the Arabian Sea along the Gulf of Oman and is in the proximity of the strategic Straits of Hormuz. Low-lying white buildings typify most of Muscat's urban landscape, while the port-district of Muttrah, with its corniche and harbour, form the north-eastern periphery of the city. Muscat's economy is dominated by trade, petroleum and porting.
