The cave was discovered by Col. William Willoughby Cole Verner, an English ornithologist who had retired in Algeciras in 1911,[1] and the famous French prehistorian L’Abbe Breuil.

This visit was also cut short as a military police officer saw them clambering up the cliff face and told them they could not do this and had to "keep to the road".

They eagerly explored the talus and were able to find some more remains including over a dozen flint tools and they described the area as having several beddings of rock falls and breccias.

[2] Between November 1925 and January 1927, the site was further investigated by Dorothy Garrod from Cambridge University at the suggestion of L’Abbe Breuil.

[1] She excavated the site intensively and succeeded in discovering another very important find, a Neanderthal Skull, now referred to as Gibraltar 2.
