The Rock of Gibraltar is a highly strategic monolithic limestone mountain 426 m (1,398 ft) high dominating the western entrance to the Mediterranean Sea. It is situated near the end of a narrow 9 kilometres (5.6 mi) long promontory stretching due south into the Mediterranean Sea and is located within the British territory of Gibraltar, and is 27 km north-east of Tarifa, Spain, the southwestern tip of Europe on the Iberian Peninsula. The rock serves as an impregnable fortress and contains a labyrinthine network of man-made tunnels known as the Tunnels of Gibraltar. Most of the Rock's upper area comprises a nature reserve which is home to about 300 Barbary macaques. It is a major tourist attraction.

Ṭāriq ibn Ziyād, also known simply as Tarik in English, was an Umayyad commander who initiated the Muslim conquest of Visigothic Hispania in 711–718 AD. He led an army and crossed the Strait of Gibraltar from the North African coast, consolidating his troops at what is today known as the Rock of Gibraltar. The name "Gibraltar" is the Spanish derivation of the Arabic name Jabal Ṭāriq, meaning "mountain of Ṭāriq", which is named after him.
