The pyramid at Meidum is thought to be just the second pyramid built after Djoser's and may have been originally built for Huni, the last pharaoh of the Third Dynasty, and continued by Sneferu. Because of its unusual appearance, the pyramid is called el-heram el-kaddaab – (False Pyramid) in Egyptian Arabic.

The Bent Pyramid rises from the desert at a 54-degree inclination, but the top section (above 47 meters) is built at a shallower angle of 43 degrees, lending the pyramid a visibly 'bent' appearance.

The Red Pyramid, also called the North Pyramid, is the largest of the pyramids located at the Dahshur necropolis in Cairo, Egypt. Named for the rusty reddish hue of its red limestone stones, it is also the third largest Egyptian pyramid, after those of Khufu and Khafre at Giza. It is also believed to be Egypt's first successful attempt at constructing a "true" smooth-sided pyramid. Local residents refer to the Red Pyramid as el-heram el-watwaat, meaning the Bat Pyramid.
The Red Pyramid was not always red. It used to be cased with white Tura limestone, but only a few of these stones now remain at the pyramid's base, at the corner. During the Middle Ages, much of the white Tura limestone was taken for buildings in Cairo, revealing the red limestone beneath.

The Great Pyramid of Giza[a] is the largest Egyptian pyramid and the tomb of Fourth Dynasty pharaoh Khufu. It is the oldest of the Seven Wonders of the Ancient World, and the only one to remain largely intact. As part of the Giza pyramid complex, it borders present-day Giza in Greater Cairo, Egypt.
The Great Pyramid was built by quarrying an estimated 2.3 million large blocks weighing 6 million tonnes in total. Primarily local limestone from the Giza Plateau was used.
