The base of a pyramid can be trilateral, quadrilateral, or of any polygon shape. As such, a pyramid has at least three outer triangular surfaces at least four faces including the base.
The square pyramid , with a square base and four triangular outer surfaces, is a common version. A pyramid's design, with the majority of the weight closer to the ground,  and with the pyramidion at the apex, means that less material higher up on the pyramid will be pushing down from above.
This distribution of weight allowed early civilizations to create stable monumental structures. Civilizations in many parts of the world have built pyramids.
For thousands of years, the largest structures on Earth were pyramids—first the Red Pyramid in the Dashur Necropolis and then the Great Pyramid of Khufu , both in Egypt —the latter is the only one of the Seven Wonders of the Ancient World still remaining.
The Mesopotamians built the earliest pyramidal structures, called ziggurats. Since they were constructed of sun-dried mud-brick, little remains of them.
Ziggurats were built by the Sumerians , Babylonians , Elamites , Akkadians , and Assyrians for local religions.
Each ziggurat was part of a temple complex which included other buildings. The precursors of the ziggurat were raised platforms that date from the Ubaid period  during the fourth millennium BC.
The earliest ziggurats began near the end of the Early Dynastic Period. Built in receding tiers upon a rectangular, oval, or square platform, the ziggurat was a pyramidal structure with a flat top.
Sun-baked bricks made up the core of the ziggurat with facings of fired bricks on the outside. The facings were often glazed in different colors and may have had astrological significance.
Kings sometimes had their names engraved on these glazed bricks. The number of tiers ranged from two to seven.
It is assumed that they had shrines at the top, but there is no archaeological evidence for this and the only textual evidence is from Herodotus.
The most famous pyramids are the Egyptian — huge structures built of brick or stone, some of which are among the world's largest constructions.
They are shaped as a reference to the rays of the sun. Most pyramids had a polished, highly reflective white limestone surface, to give them a shining appearance when viewed from a distance.
The capstone was usually made of hard stone — granite or basalt — and could be plated with gold, silver, or electrum and would also be highly reflective.
The first pyramid was erected during the Third Dynasty by the Pharaoh Djoser and his architect Imhotep. This step pyramid consisted of six stacked mastabas.
The largest Egyptian pyramids are those at the Giza pyramid complex. The age of the pyramids reached its zenith at Giza in — BC. At ft, it was the tallest building in the world until Lincoln Cathedral was finished in AD.
It is the only one to survive into modern times. The Ancient Egyptians covered the faces of pyramids with polished white limestone , containing great quantities of fossilized seashells.
Most pyramids are located near Cairo, with only one royal pyramid being located south of Cairo, at the Abydos temple complex.
The last king to build royal pyramids was Ahmose ,  with later kings hiding their tombs in the hills, such as those in the Valley of the Kings in Luxor's West Bank.
Smaller pyramids with steeper sides were also built by the Nubians who ruled Egypt in the Late Period. While pyramids are associated with Egypt, the nation of Sudan has extant pyramids, the most numerous in the world.
The pyramids of Kush, also known as Nubian Pyramids, have different characteristics than the pyramids of Egypt.
The Nubian pyramids were constructed at a steeper angle than Egyptian ones. Pyramids were still being built in Sudan as late as AD.
One of the unique structures of Igbo culture was the Nsude Pyramids , at the Nigerian town of Nsude, northern Igboland. Circular stacks continued, till it reached the top.
The structures were temples for the god Ala , who was believed to reside at the top. A stick was placed at the top to represent the god's residence.
The structures were laid in groups of five parallel to each other. Neither of these still survive and there is no evidence that they resembled Egyptian pyramids.
These buildings were not constructed in the same manner as the pyramids in Egypt. They do have inwardly sloping walls but other than those there is no obvious resemblance to Egyptian pyramids.
They had large central rooms unlike Egyptian pyramids and the Hellenikon structure is rectangular rather than square, The dating of these structures has been made from the pot shards excavated from the floor and on the grounds.
The latest dates available from scientific dating have been estimated around the 5th and 4th centuries.
Normally this technique is used for dating pottery , but here researchers have used it to try to date stone flakes from the walls of the structures.
This has created some debate about whether or not these structures are actually older than Egypt , which is part of the Black Athena controversy.
Mary Lefkowitz has criticised this research. She suggests that some of the research was done not to determine the reliability of the dating method, as was suggested, but to back up an assumption of age and to make certain points about pyramids and Greek civilization.
She notes that not only are the results not very precise, but that other structures mentioned in the research are not in fact pyramids, e.
She also notes the possibility that the stones that were dated might have been recycled from earlier constructions. She also notes that earlier research from the s, confirmed in the s by Fracchia was ignored.
She argues that they undertook their research using a novel and previously untested methodology in order to confirm a predetermined theory about the age of these structures.
Liritzis responded in a journal article published in , stating that Lefkowitz failed to understand and misinterpreted the methodology.
The structures have been dated to the 19th century and their original function explained as a byproduct of contemporary agricultural techniques.
As of November , Egyptian pyramids have been identified. It was found again only during an archaeological dig conducted in Many pyramids are in a poor state of preservation or buried by desert sands.
If visible at all, they may appear as little more than mounds of rubble. As a consequence, archaeologists are continuing to identify and study previously unknown pyramid structures.
The most recent pyramid to be discovered was that of Sesheshet at Saqqara , mother of the Sixth Dynasty pharaoh Teti , announced on 11 November All of Egypt's pyramids, except the small Third Dynasty pyramid at Zawyet el-Maiyitin , are sited on the west bank of the Nile , and most are grouped together in a number of pyramid fields.
The most important of these are listed geographically, from north to south, below. Abu Rawash is the site of Egypt's most northerly pyramid other than the ruins of Lepsius pyramid number one ,  the mostly ruined Pyramid of Djedefre , son and successor of Khufu.
Originally it was thought that this pyramid had never been completed, but the current archaeological consensus is that not only was it completed, but that it was originally about the same size as the Pyramid of Menkaure , which would have placed it among the half-dozen or so largest pyramids in Egypt.
Its location adjacent to a major crossroads made it an easy source of stone. Quarrying, which began in Roman times, has left little apart from about fifteen courses of stone superimposed upon the natural hillock that formed part of the pyramid's core.
A small adjacent satellite pyramid is in a better state of preservation. The Giza Plateau 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 Chephren , 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 of Giza.
Of the three, only Khafre's pyramid retains part of its original polished limestone casing, near its apex. This pyramid appears larger than the adjacent Khufu pyramid by virtue of its more elevated location, and the steeper angle of inclination of its construction — it is, in fact, smaller in both height and volume.
The Giza pyramid complex 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 Ancient World.
Today it is the only one of those wonders still in existence. This site, halfway between Giza and Abusir , is the location for two unfinished Old Kingdom pyramids.
The northern structure's owner is believed to be pharaoh Nebka , while the southern structure, known as the Layer Pyramid , may be attributable to the Third Dynasty pharaoh Khaba , a close successor of Sekhemkhet.
If this attribution is correct, Khaba's short reign could explain the seemingly unfinished state of this step pyramid. There are a total of fourteen pyramids at this site, which served as the main royal necropolis during the Fifth Dynasty.
The quality of construction of the Abusir 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 best preserved, Neferirkare Kakai and Sahure.
The site is also home to the incomplete Pyramid of Neferefre. Most of the major pyramids at Abusir were built using similar construction techniques, comprising a rubble core surrounded by steps of mudbricks with a limestone outer casing.
Major pyramids located here include the Pyramid of Djoser — generally identified as the world's oldest substantial monumental structure to be built of dressed stone — the Pyramid of Userkaf , the Pyramid of Teti and the Pyramid of Merikare , dating to the First Intermediate Period of Egypt.
Also at Saqqara is the Pyramid of Unas , which retains a pyramid causeway that is one of the best-preserved in Egypt. Together with the pyramid of Userkaf, this pyramid was the subject of one of the earliest known restoration attempts, conducted by Khaemweset , a son of Ramesses II.
Archaeologists believe that had this pyramid been completed, it would have been larger than Djoser's. Most of these are in a poor state of preservation.
The Fourth Dynasty pharaoh Shepseskaf either did not share an interest in, or have the capacity to undertake pyramid construction like his predecessors.
His tomb, which is also sited at south Saqqara, was instead built as an unusually large mastaba and offering temple complex.
A previously unknown pyramid was discovered at north Saqqara in late This area is arguably the most important pyramid field in Egypt outside Giza and Saqqara, although until the site was inaccessible due to its location within a military base and was relatively unknown outside archaeological circles.
The southern Pyramid of Sneferu , commonly known as the Bent Pyramid , is believed to be the first Egyptian pyramid intended by its builders to be a "true" smooth-sided pyramid from the outset; the earlier pyramid at Meidum had smooth sides in its finished state, but it was conceived and built as a step pyramid, before having its steps filled in and concealed beneath a smooth outer casing of dressed stone.
As a true smooth-sided structure, the Bent Pyramid was only a partial success — albeit a unique, visually imposing one; it is also the only major Egyptian pyramid to retain a significant proportion of its original smooth outer limestone casing intact.
As such it serves as the best contemporary example of how the ancient Egyptians intended their pyramids to look.
Several kilometres to the north of the Bent Pyramid is the last — and most successful — of the three pyramids constructed during the reign of Sneferu; the Red Pyramid is the world's first successfully completed smooth-sided pyramid.
The structure is also the third largest pyramid in Egypt, after the pyramids of Khufu and Khafra at Giza. Also at Dahshur is one of two pyramids built by Amenemhat III , known as the Black Pyramid , as well as a number of small, mostly ruined subsidiary pyramids.
Located to the south of Dahshur, several mudbrick pyramids were built in this area in the late Middle Kingdom , perhaps for Amenemhat IV and Sobekneferu.
Two major pyramids are known to have been built at Lisht: those of Amenemhat I and his son, Senusret I. The latter is surrounded by the ruins of ten smaller subsidiary pyramids.
One of these subsidiary pyramids is known to be that of Amenemhat's cousin, Khaba II. 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, that attribution is uncertain, as no record of Huni's name has been found at the site. It was constructed as a step pyramid and then later converted into the first "true" smooth-sided pyramid, when the steps were filled in and an outer casing added.
The pyramid suffered several catastrophic collapses in ancient and medieval times. Medieval Arab writers described it as having seven steps, although today only the three uppermost of these remain, giving the structure its odd, tower-like appearance.
The hill on which the pyramid is situated is not a natural landscape feature, it is the small mountain of debris created when the lower courses and outer casing of the pyramid gave way.
Amenemhat III was the last powerful ruler of the Twelfth Dynasty, and the pyramid he built at Hawara, near the Faiyum, is believed to post-date the so-called " Black Pyramid " built by the same ruler at Dahshur.
It is the Hawara pyramid that is believed to have been Amenemhet's final resting place.
