Jebel Musa (Amazigh: Adrar Musa) is the name given to a mountain located in the northernmost part of Morocco on the African side of the Straits of Gibraltar. Together with the Rock of Gibraltar to the north, it is known as one of the Pillars of Hercules (although this title is also claimed by Monte Hacho in the Spanishexclave of Ceuta, some kilometres to the east of the mountain). It is 851 m (2,790 ft) high.
