Sur is the capital city of Ash Sharqiyah South Governorate, and the former capital of Ash Sharqiyah Region in northeastern Oman, on the coast of the Gulf of Oman.
By the 6th century, Sur was an established centre for trade with East Africa.
Ibn Battuta commented on his visit to this “roadstead of a large village on the seashore.” In the 16th century, it was under Portuguese rule but was liberated by the Omani Imam Nasir ibn Murshid and underwent an economic revival, as a trade centre with India and East Africa. This continued until the mid-19th century, when the British outlawed the slave trade. The city was further ruined by the opening of the Suez Canal, which saw it lose trade with India.
Sur City port which is one of the oldest ports in the world played a very important role in forming the trade with more than one hundred and fifty sailing ships daily during the eighteenth and nineteenth centuries.
