The Rock of Gibraltar is a monolithic limestone promontory located in the British territory of Gibraltar, near the southwestern tip of Europe on the Iberian Peninsula, and near the entrance to the Mediterranean. It is 426 m high. Most of the Rock’s upper area is covered by a nature reserve.

You can walk up and around on the rock after paying some admission. There are a few tourist sites and museums, but (at least in 2012) you can also roam around freely and explore the left-over fortification buildings and narrow, winding footpaths.
