Extracts from the following book – Places not on Google Maps
In the deserts just over the border from Northern Sudan stand nine perfect cubes in three rows of three, aligned with where the sun would have risen on the eastern horizon in 7,721BC. Each of the cubes is 9 Royal Cubits in height, width, and depth. There is evidence of water erosion. Each cube is 27 royal cubits from any other cube. There are no markings on the cubes, no symbols, no references to gods or pharaohs. Rock is the same as that at the Giza Plateau, limestone. There is a passageway under the centre cube, leading to an unknown place, perhaps to the Hall of Secrets.
