Jeddah (sometimes spelled Jiddah or Jedda ; English pronunciation: /ˈdʒɛdə/; Arabic: جدة Jiddah or Jaddah, IPA: [ˈdʒedda, ˈdʒidda]) is a city in the Hijaz Tihamah region on the coast of the Red Sea and is the major urban center of western Saudi Arabia. It is the largest city in Makkah Province, the largest sea port on the Red Sea, and the second-largest city in Saudi Arabia after the capital city, Riyadh. With a population currently at 3.4 million people, Jeddah is an important commercial hub in Saudi Arabia.Jeddah is the principal gateway to Mecca, Islam's holiest city, which able-bodied Muslims are required to visit at least once in their lifetime. It is also a gateway to Medina, the second holiest place in Islam.Economically, Jeddah is focusing on further developing capital investment in scientific and engineering leadership within Saudi Arabia, and the Middle East. Jeddah was independently ranked fourth in the Africa – Mid-East region in terms of innovation in 2009 in the Innovation Cities Index.Jeddah is one of Saudi Arabia's primary resort cities and was named a Gamma world city by the Globalization and World Cities Study Group and Network (GaWC). Given the city's close proximity to the Red Sea, fishing and sea food dominates the food culture unlike other parts of the country. The city has been labeled as 'different' by the majority of Saudis in an effort to promote tourism in the city, that had been previously perceived as 'most open' city in Saudi Arabia.Historically, Jeddah has been well known for its legendary money changers. The largest of said money changers at the time (the late Sheikh Salem Bin Mahfouz) eventually founded Saudi Arabia's first bank, the National Commercial Bank (NCB).
