The architecture of this period was similar to that seen at Giza royal necropolis of the Fourth Dynasty, where recent excavations have revealed that the essential focus of the kingdom at that time centred on the construction of the royal tombs. A strong suggestion of this notion is the etymology of the name of the city itself, which matched that of the pyramid of Pepi I of the Sixth Dynasty. Memphis was then the heir to a long artistic and architectural practice, constantly encouraged by the monuments of preceding reigns.
