Egypt is home to some strangely structured caves that are loaded with history predating Ancient Egypt, Egypt Today reports. The Djarra cave in the Western Desert is home to pure groundwater and has Neolithic engravings of animals; it’s thought to have been an important Stone Age settlement. The Foggeni cave was discovered recently in 2002 and is considered incredibly rich in terms of prehistoric art, earning the nickname “Cave of Beasts.” We went with the Sannur cave for our image pick because of its spectacular colours and unique topography.
