<P> The Great Pyramid is surrounded by a complex of several buildings including small pyramids . The Pyramid Temple, which stood on the east side of the pyramid and measured 52.2 metres (171 ft) north to south and 40 metres (130 ft) east to west, has almost entirely disappeared apart from the black basalt paving . There are only a few remnants of the causeway which linked the pyramid with the valley and the Valley Temple . The Valley Temple is buried beneath the village of Nazlet el - Samman; basalt paving and limestone walls have been found but the site has not been excavated . The basalt blocks show "clear evidence" of having been cut with some kind of saw with an estimated cutting blade of 15 feet (4.6 m) in length, capable of cutting at a rate of 1.5 inches (38 mm) per minute . John Romer suggests that this "super saw" may have had copper teeth and weighed up to 300 pounds (140 kg). He theorizes that such a saw could have been attached to a wooden trestle and possibly used in conjunction with vegetable oil, cutting sand, emery or pounded quartz to cut the blocks, which would have required the labour of at least a dozen men to operate it . </P> <P> On the south side are the subsidiary pyramids, popularly known as Queens' Pyramids . Three remain standing to nearly full height but the fourth was so ruined that its existence was not suspected until the recent discovery of the first course of stones and the remains of the capstone . Hidden beneath the paving around the pyramid was the tomb of Queen Hetepheres I, sister - wife of Sneferu and mother of Khufu . Discovered by accident by the Reisner expedition, the burial was intact, though the carefully sealed coffin proved to be empty . </P> <P> The Giza pyramid complex, which includes among other structures the pyramids of Khufu, Khafre and Menkaure, is surrounded by a cyclopean stone wall, the Wall of the Crow . Mark Lehner has discovered a worker's town outside of the wall, otherwise known as "The Lost City", dated by pottery styles, seal impressions, and stratigraphy to have been constructed and occupied sometime during the reigns of Khafre (2520--2494 BC) and Menkaure (2490--2472 BC). Recent discoveries by Mark Lehner and his team at the town and nearby, including what appears to have been a thriving port, suggest the town and associated living quarters consisting of barracks called "galleries" may not have been for the pyramid workers after all, but rather for the soldiers and sailors who utilized the port . In light of this new discovery, as to where then the pyramid workers may have lived Lehner now suggests the alternative possibility they may have camped on the ramps he believes were used to construct the pyramids or possibly at nearby quarries . </P> <P> In the early 1970s, the Australian archaeologist Karl Kromer excavated a mound in the South Field of the plateau . This mound contained artefacts including mudbrick seals of Khufu, which he identified with an artisans' settlement . Mudbrick buildings just south of Khufu's Valley Temple contained mud sealings of Khufu and have been suggested to be a settlement serving the cult of Khufu after his death . A worker's cemetery used at least between Khufu's reign and the end of the Fifth Dynasty was discovered south of the Wall of the Crow by Zahi Hawass in 1990 . </P>
