Brome also discovered Genista II which was a smaller cave. Genista III and Genista IV followed and all showed some evidence of habitation but Genista four was very inaccessible and was thought be a place of refuge rather than a place to live as its entrance was forty feet down from the summit on a cliff face of the Rock of Gibraltar. Most of the Genista floors are covered in stalagmites and investigators found human remains, pottery and broken bones. One possibility is that the caves were used as a place to live but after being abandoned they were reused as burial places.
