The Rock of Gibraltar is a monolithic limestone promontory located at the southwestern tip of the Iberian Peninsula. It is often also called the Pillar of Hercules. It is 426 metres (1,396 feet) high. Most of the upper parts of the Rock is a nature reserve, and home to a 250-strong colony of Barbary Macaques, the only wild monkeys found in Europe.
The Rock of Gibraltar was also known by its Latin name Calpe and its Greek name Mons Calpe. It is one of the two Pillars of Hercules, the other being Mons Abyla on the other side of the strait.
Many parts of the Rock of Gibraltar are tourist attractions. Half way up the western slope is St Michael's Cave. On the steep eastern face is Gorham's Cave. There is also the ruins of a Moorish Castle on the Rock.
