1. Historical background
Egypt has many unexplored archeological sites. The archeologists know where to search, but they like to know more where to dig. Two archeological sites are selected in the southern part of Dahshour area for the application of the detailed magnetic measurements (Fig. 1). The Dahshour region is a part of the Memphis necropolis (cemetery), the capital of the old kingdom, extends from Abu Roah in the north to Meidum in the south. King Senefru from 4th Dynasty (old kingdom) has built two pyramids at Dahshour area using limestone blocks; the red pyramid in the north and the pent pyramid in the south. The kings Amenemhat III and Senusert III of middle kingdom had built their pyramids from mud bricks. Definitely the surveys are carried out at a tomb, natively called “Mastaba” and an archeological hill, natively called “Tell Athery” which belonged to princes and princesses of the old kingdom.
