Location:

It is located to the Southwest of Memphis at some 10 kilometres to the South of Saqqara and some 40 kilometres North of Meidum , Dashur is the most southern site of the Memphite necropolis, which stretches to Abu Rawash in the North. How to reach: By vehicle: If you need a private transfer, Memphis tours can arrange that for you by Air-conditioned modern

vehicle from anywhere in Cairo or Giza. 

Sightseeing: 

On a clear day, the two pyramids built there by Snofru , the founder of the 4th Dynasty, as well as the mountain-like remains of the pyramid of Amenemhat III can easily be seen from Saqqara to the North and Meidum to the South, or even from Egypt's modern-day capital Cairo, which lies some 50 kilometres to the North. Dashur owes its modern-day name to the nearby villages Dashur and Minsat Dashur. This name may perhaps come from the Coptic name Tahsur, or Takuris in Greek.

This southernmost part of the Memphite necropolis stretches an area of approximately 3 to 3.5 kilometres from South to North and 2 to 2.5 kilometres East to West. It starts at about 1.5 kilometres to the West of the fertile ground. The first pyramid was built in the Southwestern corner of the Dashur area, to the Northwest of a lake and at quite some distance into the desert. This pyramid was started at an angle of 54°27'44", but about halfway, the angle was changed to 43°22'. This bend in the sides of the pyramid has given it its modern-day name: the Bent Pyramid. Perhaps because the change of angle did not conform to the new ideology, Snofru started a second pyramid, at some distance to the North of the Bent Pyramid. This new pyramid is often called the Red Pyramid because of its reddish appearance. The West side of the Bent Pyramid roughly aligns with the East side of the Red Pyramid. The angle of the Red Pyramid is the same as the top part of the Bent Pyramid: 43°22'. 

The small pyramid to the Northeast of the Red Pyramid has never been completed. Archaeological research has shown it to date to the 4th Dynasty as well, but it is not clear for whom it was built. At about the same time, several private tombs were constructed to the east of the two pyramids. One of Snofru's sons, a man named Kanefer, was buried in one of the tombs closest to the Red Pyramid. The first notable building activity in the area after Snofru is dated to the reign of Amenemhat II of the 12th Dynasty, who chose to build his pyramid near the cluster of Old Kingdom tombs where Kanefer was buried. His example would be followed by Sesostris III , who moved slightly to the North, and Amenemhat III , more to the South. The Middle Kingdom pyramids at Dashur were built closer to the edge of fertile land. Amenemhat III abandoned his pyramid, probably because it was being built on unstable desert sand. At least the Northern part of Dashur continued to be used as a necropolis for private burials during the New Kingdom . More research and archaeological fieldwork are needed to reveal the full history of the southernmost part of the Memphite necropolis. After the Middle Kingdom, Dashur seems to have lost its appeal as a royal necropolis. Amenemhat III's pyramid was the last royal funerary monument that was built there. Recent archaeological research, however, has revealed a private necropolis dated to the New Kingdom at North Dashur.

Why was it built ? 

The Bent Pyramid was built as the ancient Egyptians believe in resurrection. Snefru was buried in this pyramid according to the ancient Egyptian concept of life after death. Explanation: This pyramid is famous for its casing which is the best in all the pyramids of Egypt. Its original height is 336 feet and the pyramid itself has two separate entrances. Mysteriously, this pyramid started at one angle (approx. 52 degrees) and then suddenly changes to a more gradual angle of 43 degrees. This odd arrangement provides this pyramid with a distinctive and unique appearance. 

There are several possible reasons for this change in angle. Currently, the most widely accepted theory is that King Sneferu realized that if he were to continue the pyramid at its initial angle, it would rise to a height which would require a tremendous amount of material and labor. Another theory holds that the original angle resulted in displacement of many blocks and cracking of the blocks that lined the chambers and passageways.
