The city of Al Jubayl (or Jubail) is located on the coast of Saudi Arabia, along the Persian Gulf. The city has a history extending back more than 7,000 years, but since 1975 it has been associated with the petrochemical, fertilizer, and steel industries. At night, these industrial areas form a brightly lit region (image center) to the south of the residential and commercial center of Al Jubayl (characterized by green-gray lighting). An artificial peninsula extending into the Persian Gulf to the northeast hosts supertanker docks and petroleum storage facilities.
