Jeddah or Jiddah, is a Saudi Arabian city located 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. The population of the city currently stands at over 3.4 million. It is an important modern 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. 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.
