Nearly all Fourth Dynasty kings chose a different location for their pyramids. During the second half of the Old Kingdom, under the Fifth and Sixth Dynasties, Saqqara was again the royal burial ground. The Fifth and Sixth Dynasty pyramids are not built wholly of massive stone blocks, but instead with a core consisting of rubble. Consequently, they are less well preserved than the world-famous pyramids built by the Fourth Dynasty kings at Giza. Unas, the last ruler of the Fifth Dynasty, was the first king to adorn the chambers in his pyramid with Pyramid Texts. During the Old Kingdom, it was customary for courtiers to be buried in mastaba tombs close to the pyramid of their king. Thus, clusters of private tombs were formed in Saqqara around the pyramid complexes of Unas and Teti.
