Fact 2 on the Red Pyramid:
The first construction was the completion of the Meidum pyramid near Crocodilopolis in the Faiyum. The second construction was the 'Bent Pyramid' at Dahshur which was first attempt to construct a smooth-sided pyramid. The angle was too steep and resulted in the bent shape. The slope of the lower part of the Bent pyramid had a 55-degree inclination, but the top section was built at the shallower angle of 43 degrees.
Fact 3 on the Red Pyramid:
The building was located 4 km north of the bent pyramid.
Fact 4 on the Red Pyramid:
Lessons were learned in respect of the construction and architecture of the 'Bent Pyramid' and King Snefru went on to build the Red Pyramid.

By the time it was completed, it would be the tallest man-made structure in the world. It remains the fourth highest ever built, only the great Giza pyramids were taller.
Fact 6 on the Red Pyramid:
The ancient Egyptian architects designed the new monument from the start with the shallower angle of 43 degrees.
Fact 7 on the Red Pyramid:
The stones on this structure were layered in horizontal lines, rather than in a slope and it was built on a broader base in order to spread the mass of the structure and avoid the problems encountered when building the previous 'Bent Pyramid'.
Fact 8 on the Red Pyramid:
The great monument was originally enclosed with the gleaming white limestone from the Stone quarry at Tura.
Fact 9 on the Red Pyramid:
However, the shallow slope made the white limestone a target for stone robbers who removed the covering and the oxidation process of the remaining limestone changed its color to red.
Fact 10 on the Red Pyramid:
Some historians believe that Snefru was buried in this pyramid, although his mummy has never been found.
