Inside the Rock of Gibraltar
The Rock of Gibraltar is mainly limestone. It is dissolved by rainwater which creates large caverns in the center of the rock. Some of the dissolved limestone is left behind as the water evaporates and runs over the harder surfaces or drips onto the floor of the cave. This creates spectacular formations of stalactites and stalagmites.
The forms are flowing, and have been for thousands of years. With the rain outside, it is a welcome place to take shelter.
The guides like to share a little verse to help remember the difference between stalactites and stalagmites. They say “the tights go down and the mites mound up”.
The addition of color lights emphasises the form and depth of the caves.
The colors change frequently,
and it is possible to over do it.
In 1974 ancient paintings were found on the cave walls and dated to 15-20 thousand years ago. Recently a Neolithic bowl and two Neanderthal skulls were found in Gibraltar suggesting inhabitation since 40,000 BC.
Remember, without the lights, it will be extremely dark inside the caves.
Don’t lose track of the exit.
