A pyramid is any three-dimensional structure where the upper surfaces are triangular and converge on one point. The base of a pyramid is usually quadrilateral or trilateral (but generally it can be any polygon shape), meaning that a pyramid usually has three or four sides (but theoretically there is no limit to the number of sides a pyramid can generally have), but all pyramids must have trilateral sides. The measurements of these triangles uniformly classify the shape as isosceles and sometimes equilateral.

A pyramid's design, with the majority of the weight closer to the ground, means that less material higher up on the pyramid will be pushing down from above. This allowed early civilizations to create stable monumental structures. 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, the only remaining Wonder of the World.

Pyramid-shaped structures were built by many ancient civilizations.

Egyptian pyramids

The most famous pyramids are the Egyptian pyramids — huge structures built of brick or stone, some of which are among the largest man-made constructions.

Pyramids functioned as tombs for pharaohs. The Great Pyramid of Giza is the largest in Egypt and one of the largest in the world. It is one of the Seven Wonders of the World, and the only one of the seven to survive into modern times. The ancient Egyptians capped the peaks of their pyramids with gold and covered their faces with polished white limestone, though many of the stones used for the purpose have fallen or been removed for other structures over the millennia.

The inspiration for Egypt's pyramids is a subject of debate. Some Egyptologists have seen King Djoser's Step Pyramid as a symbolic representation of ancient Egypt's stratified society. A more recent hypothesis by Patricia Blackwell Gary and Richard Talcott ("Stargazing in Ancient Egypt," Astronomy, June 2006, pp. 62-67) derives the shapes of the pyramid and of the obelisk from natural phenomena associated with the sun (the sun-god Re being the Egyptians' greatest deity). The pyramid and obelisk would have been inspired by previously overlooked astronomical phenomena connected with sunrise and sunset: the zodiacal light and Sun pillars, respectively.

Most Egyptians prepared for death; they tried to provide a secure resting place that would last an eternity. Although this was their wish, it did not work that way. Often times the weather and tomb robbers were the main culprits that destroyed many tombs. Most tomb robbers, who were believed to be the tomb builders, often reentered the tomb after it was sealed, unwrapping the mummy and removing all amulets and stones. The coffins made of wood, which also held many precious stones, where also picked and destroyed. After destroying the tomb, many of the mummies would be taken out and burnt for fuel or sold as a souvenir product. Although tomb robbers were the main culprits, modern cultures also influenced the desecration of many mummies.

Nubian pyramids

Nubian pyramids were constructed (roughly 220 of them) at three sites in Nubia to serve as tombs for the kings and queens of Napata and Meroë.

The Nubians built far more than the Egyptians, but they are much smaller. The Nubian pyramids were constructed at a much steeper angle than Egyptian ones and were not tombs, but monuments to dead kings. Pyramids were built in Nubia up to AD 300.

Mesopotamians pyramids

The Mesopotamians also built pyramids, called ziggurats.

In ancient times these were brightly painted. Since they were constructed of mud-brick, little remains of them. The Biblical Tower of Babel is believed to have been a Babylonian ziggurat.

Mesoamerican pyramids

A number of Mesoamerican cultures also built pyramid-shaped structures. Mesoamerican pyramids were usually stepped, with temples on top, more similar to the Mesopotamian ziggurat than the Egyptian pyramid. The largest pyramid by volume is the Great Pyramid of Cholula, in the Mexican state of Puebla. This pyramid is considered the largest monument ever constructed anywhere in the world, but it is still being excavated. There is an unusual pyramid with a circular plan at the site of Cuicuilco, now inside Mexico City and mostly covered with lava from an ancient eruption of Xictli.Pyramids in Mexico were often used as places of sacrifice.


There is a Roman era pyramid built in Falicon, France.

Ancient Rome

Pyramid of Cestius
Pyramid of Cestius

There is a pyramid in ancient Rome. The 27-meter-high Pyramid of Cestius was built by the end of the first century BC and still exists today, close to the Porta San Paolo. Another one, named Meta Romuli, standing in the Ager Vaticanus (today's Borgo), was destroyed at the end of the 15th century.


There are a few flat-top pyramids in China. The First Emperor of Qin (circa 221 B.C.), with the terracotta warriors in the vicinity, was buried under a large pyramid outside modern day Xi'an. In the following centuries about a dozen more Han Dynasty royals were also buried under flat top pyramidal earth works.

Ancient Greece

There are several structures in Greece that archaeologists have called pyramids. Dotted throughout the landscape are remains of buildings that were described by ancient travelers as pyramids. They were first excavated by the Americans and the Germans in the early 1930s and the 1990s.

Pausanias, a Greek traveler in the second century A.D. described several of the structures as pyramids. One of these pyramids was located in Helliniko,Ελληνικό in Greek,a village near Argos near the ancient ruins of Tiryns. The story surrounding the monument was that it was built as a polyandria, a common grave, for those soldiers who had fallen in the struggle for the throne of Argos back in the 14th Century B.C. He described the structure as something that resembled a pyramid with the decorations of Argolic shields, showing the military connection to it. Another pyramid that Pausanias saw on his journeys was at Kenchreai, another polyandria dedicated to the Argives and Spartans who lost their lives at the Battle of Hysiai in 669 B.C. Unfortunately neither of these structures remain fully intact today to test how closely they resembled the pyramids of Egypt nor is there any proof that they even resembled an Egyptian pyramid at all.

There are two surviving pyramid-like structures still available to study, one at Helleniko and the other at Ligourio,a village near the ancient theatre Epidaurus. With these two pyramid’s base stones remaining, it is possible to determine that Grecian pyramids existed, but were not used as the Egyptians used them. These buildings were not constructed in the same manner as the pyramids in Egypt. The buildings at Helleniko and Ligourio were no more than 100 feet tall and were surrounded by walls, with the base of the Helleniko pyramid being nine meters by 7 meters. The stones used to build the pyramids was limestone quarried locally and were cut to fit together, not into freestanding blocks like the Great Pyramid of Giza. The base of the structure also differed from the Egyptians pyramids as they were rectangular, not square. This simple construction shape made it very difficult to make the top of the building come together in a point. As such, it makes more sense that these structures could have been peaked by a roof or platform.

They also differ from Egypt’s monuments in that the functional roles of these buildings were not funerary tombs, but they gave a service to the living. There are no remains or graves in or near the structures. Instead, the rooms that the walls housed were made to be locked from the inside. This coupled with the platform roof, means that one of the functions these structures could have served was as watchtowers. Another possibility for the buildings is that they are shrines to heroes and soldiers of ancient times, but the lock on the inside makes no sense for such a purpose.

The dating of these ‘pyramids’ 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. There are many researchers who have given dates to the structures that pre-date the pyramids at Giza, but the method to obtain these dates was thermoluminescence of the stone. Normally this technique is used for dating pottery, but here researchers have used it to try and date stone flakes from the walls of the structures. This has created some debate about whether or not these ‘pyramids’ are actually older than Egypt, which is part of the Black Athena controversy. The basis for their use of thermoluminescence in order to date these structures is a new method of collecting samples for testing. Scientists from laboratories hired out by the recent excavators of the site, The Academy of Athens, say that they can use the electrons trapped on the inner surface of the stones to positively identify the date that the stones were quarried and put together.

The problem with this method is that they date the pyramids with a margin of error of up to over 700 years. This method dated the Helleniko pyramid to 2730 B.C. with an error factor of plus or minus 720 years. It also dated the Ligourio pyramid to 2260 B.C. with an error of plus or minus 710 years. Though these initial dates are indicative of these structures being built before the pyramid complex at Giza, it also means that they could have been built well after Khufu’s Great Pyramid was erected. Some archaeologists, however, have indicated that these samples may have been very select in their choice of which stones to sample. Further excavations of the site at Helleniko reveal that it was constructed on a previously existing structure, giving a possibility that the new methods of dating may be a misinterpretation.

Along with these two structures there are 14 more pyramid-like buildings, or their remains, scattered throughout the rest of the country side of Greece. These sites do not get as much attention as the two at Helleniko and Ligourio as they are the only ones mentioned in surviving accounts of ancient travelers.

Pyramids have occasionally been used in Christian architecture of the feudal era, e.g. as the tower of Oviedo's Gothic Cathedral of San Salvador. In some cases this leads to speculations on masonic or other symbolical intentions.

An example of a modern pyramid can be found in Paris, France, in the court of the Louvre Museum. The Louvre Pyramid is a 20.6 meter (about 70 foot) glass structure which acts as an entrance to the museum. It was designed by the American architect I. M. Pei and completed in 1989.
