Rock of Gibraltar. The Rock of Gibraltar, also known as the Rock, is a monolithic limestone promontory located in the territory of Gibraltar, near the southwestern tip of Europe on the Iberian Peninsula.
It is 426 m high. Most of the Rock's upper area is covered by a nature reserve, which is home to around 300 Barbary macaques.
These macaques, as well as a labyrinthine network of tunnels, attract many tourists each year. The Rock of Gibraltar was one of the two Pillars of Hercules and was known to the Romans as Mons Calpe, the other pillar being Mons Abyla or Jebel Musa on the African side of the Strait.
In ancient times, the two points marked the limit to the known world, a myth originally fostered by the Greeks and the Phoenicians. Gibraltar is surrounded by the Mediterranean Sea.
The Rock of Gibraltar is a monolithic promontory. The Main Ridge has a sharp crest with peaks over 400 m above sea level, formed by Early Jurassic limestones and dolomites. It is a deeply eroded and highly faulted limb of an overturned fold. The sedimentary strata composing the Rock of Gibraltar are overturned, with the oldest strata overlying the youngest strata. These strata are the Catalan Bay Shale Formation, Gibraltar Limestone, Little Bay Shale Formation, and Dockyard Shale Formation. These strata are noticeably faulted and deformed. Predominantly of shale, the Catalan Bay Shale Formation also contains thick uni
