Port-Gentil or Mandji (1993 est. pop. 80,000) is the second-largest city of Gabon, and its leading seaport. It is the center of Gabon's petroleum and timber industries. Although it lies inshore, the nearby mainland is a remote forest area and it is not connected by road to the rest of the nation. The city lies close to Cape Lopez, the westernmost point in Gabon.
