Jebel Musa (Arabic: جبل موسى, Jabal Mūsā; Berber languages: Adrar n Musa; meaning "Mount Moses") is a mountain in the northernmost part of Morocco, on the African side of the Strait of Gibraltar. It is part of the Rif mountain chain. The mountain is claimed by some to be the southern Pillar of Hercules, Mons Abila (Mount Abila or Abyla).
Monte Hacho is a low mountain that overlooks the Spanish city of Ceuta, on the north coast of Africa. Monte Hacho is positioned on the Mediterranean coast at the Strait of Gibraltar opposite Gibraltar, and along with the Rock of Gibraltar is claimed by some to be one of the Pillars of Hercules (the other candidate for the southern pillar being Jebel Musa). According to the legend, Hercules pushed apart the two mountains and created a link between the Mediterranean and the Atlantic.
In classical civilization it was possibly known as Mons Abila (Mount Abila or Abyla), although this title could refer to Jebel Musa instead.
