Pyramids in Egypt

In 1842 Karl Richard Lepsius made a list of pyramids in Egypt, in which he counted 67, but more have been identified and discovered since his time. The imprecise nature of the count is related to the fact that as many smaller pyramids are in a poor state of preservation and appear as little more than mounds of rubble, they are only now being properly identified and studied by archaeologists.
Giza is the location of the Pyramid of Khufu (also known as the "Great Pyramid" and the "Pyramid of Cheops"); the somewhat smaller Pyramid of Khafre (or Kephren); the relatively modest-sized Pyramid of Menkaure (or Mykerinus), along with a number of smaller satellite edifices known as "Queen's pyramids"; and the Great Sphinx.The Giza Necropolis has been a popular tourist destination since antiquity, and was popularized in Hellenistic times when the Great Pyramid was listed by Antipater of Sidon as one of the Seven Wonders of the World. Today it is the only one of those wonders still in existence.
Zawyet el'Aryan : This site, halfway between Giza and Abu Sir, is the location for two unfinished Old Kingdom pyramids. The northern structure's owner is believed to be the Pharaoh Nebka, whilst the southern structure is attributed to the Third Dynasty Pharaoh Khaba, also known as Hudjefa, successor to Sekhemkhet.
Abu Sir : This site, There are a total of seven pyramids at this site, which served as the main royal necropolis during the Fifth Dynasty. The quality of construction of the Abu Sir pyramids is inferior to those of the Fourth Dynasty, perhaps signaling a decrease in royal power or a less vibrant economy. They are smaller than their predecessors, and are built of low-quality local limestone. The three major pyramids are those of Niuserre (which is also the most intact), Neferirkare Kakai and Sahure. The site is also home to the incomplete Pyramid of Neferefre.
Dahshur : This area is arguably the most important pyramid field in Egypt outside Giza and Saqqara, although until 1996 the site was inaccessible due to its location within a military base, and hence was virtually unknown outside archaeological circles.
Mazghuna Located to the south of Dahshur, this area was used in the First Intermediate Period by several kings who constructed their pyramids out of mudbrick. Today these structures are obscure and unimpressive.
Sneferu's Pyramid at Meidum; the central core structure remains, surrounded by a mountain of rubble from the collapsed outer casing. The pyramid at Meidum is one of three constructed during the reign of Sneferu, and is believed by some to have been started by that pharaoh's father and predecessor, Huni. However, this is not very likely, as his name does not appear on the site. Some archaeologists also suggest that the Meidum pyramid may have been the first unsuccessful attempt at the construction of a "true" or smooth-sided pyramid.
Hawara : Amenemhet III was the last powerful ruler of the 12th Dynasty, and the pyramid he built at Hawarra, near Faiyum, is believed to post-date the so-called "Black Pyramid" built by the same ruler at Dahshur. It is the Hawarra pyramid that is believed to have been Amenemhet's final resting place.
El-Lahun : The pyramid of Senusret II at el-Lahun is the southernmost royal-tomb pyramid structure in Egypt. Its builders reduced the amount of work necessary to construct it by ingeniously using as its foundation and core a 12-meter-high natural limestone hill.
