Pyramids








China

There are many flat-topped mound tombs in China. The First Emperor of Qin (circa 221 B.C.) was buried under a large mound outside modern day Xi'an. In the following centuries about a dozen more Han Dynasty royals were also buried under flat-topped pyramidal earthworks.

Egyptian pyramids

The ancient pyramids of Egypt

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. Most of them took about 27 years to build. In Ancient Egyptian, a pyramid was referred to as mer, which was also their word for the country of Egypt itself, showing how intrinsic the structures were to the culture.[1] The Great Pyramid of Giza is the largest in Egypt and one of the largest in the world. Until Lincoln Cathedral was built in 1300 A.D., it was the tallest building in the world. The base is over 52,600 square meters in area.
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.

France

There is a Roman era pyramid built in Falicon, France. There were many more pyramids built in France in this period.

Greece

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

Pyramid of Hellinikon

Pausanias, a Greek traveler in the second century A.D. described several of the structures as pyramids. One of these pyramids was located in Hellenikon, Ελληνικό in Greek,a village near Argos near the ancient ruins of Tiryns.[2] 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 30 meters tall and were surrounded by walls, with the base of the Helleniko pyramid being nine meters by 7 meters. The stone used to build the pyramids was limestone quarried locally and was cut to fit, not into freestanding blocks like the Great Pyramid of Giza. The base of the structures also differed from the Egyptian 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.

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 issue 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.

India

Many giant granite temple pyramids were made in South India during the Chola Empire, many of which are still in religious use today. Examples of such pyramid temples include Brihadisvara Temple at Thanjavur, the Temple of Gangaikondacholisvaram and the Airavatesvara Temple at Darasuram. However the largest temple pyramid in the area is Sri Rangam in Srirangam, Tamil Nadu. The Brihadisvara Temple was declared by UNESCO as a World Heritage Site in 1987; the Temple of Gangaikondacholisvaram and the Airavatesvara Temple at Darasuram were added as extensions to the site in 2004.[3]

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, and 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 human sacrifice.

Mesopotamian 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.

North American pyramids

Many mound-building societies of ancient North America built large pyramidal earth structures known as platform mounds. Among the largest and best-known of these structures is Monk's Mound at the site of Cahokia, which has a base larger than that of the Great Pyramid at Giza. While the North American mounds' precise function is not known, they are believed to have played a central role in the mound-building people's religious life.

Nubian pyramids (Sudan)

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 more pyramids than the Egyptians, but they are smaller. The Nubian pyramids were constructed at a steeper angle than Egyptian ones and were monuments to dead kings and queens.[4]
Pyramids were still being built in Nubia up to AD 300.

Rome

Pyramid of Cestius.

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.
These Roman imitations of Egyptian monuments are important as contemporary "portraits" of the Egyptian ones, providing some sense of their original color and smoothness.

Medieval Europe

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.

Modern pyramids

The Louvre Pyramid, a modern pyramid built as an entrance to the Louvre Museum in Paris
Examples of modern pyramids are:
The Louvre Pyramid in Paris, France, in the court of the Louvre Museum, 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.
The Transamerica Pyramid in San Francisco, California, designed by William Pereira.
The 32-story Pyramid Arena in Memphis, Tennessee (built in 1991) was the home court for the University of Memphis men's basketball program, and the National Basketball Association's Memphis Grizzlies until 2004.
The Slovak radio building in Bratislava, Slovakia. This building is shaped like an inverted pyramid.
The Walter Pyramid, home of the basketball and volleyball teams of the California State University, Long Beach, campus in California, United States, is an 18-story-tall blue pyramid.
The Luxor Hotel in Las Vegas, United States, is a 30-story pyramid with light beaming from the top.
The Summum Pyramid, a 3 story pyramid in Salt Lake City, Utah, used for instruction in the Summum philosophy and conducting rites associated with Modern Mummification.
The Palace of Peace and Reconciliation in Astana, Kazakhstan.
The three pyramids of Moody Gardens in Galveston, Texas.
The Co-Op Bank Pyramid or Stockport Pyramid in Stockport, England is a large pyramid-shaped office block in Stockport in England. (The surrounding part of the valley of the upper Mersey has sometimes been called the "Kings Valley" after the Valley of the Kings in Egypt.)
The GoJa Music Hall in Prague.
The Muttart Conservatory greenhouses in Edmonton, Alberta.
The unfinished Ryugyong Hotel in Pyongyang.
Small pyramids similar to those of the Louvre can be found outside the lobby of the Citicorp Building in Long Island City, Queens NY.
The Pyramids of the City Stars Complex in Cairo, Egypt.
Pyramid building belonging to 3DPLM Software Solutions, at Hinjwadi, Pune, India.[5]

An American Green Skyscraper in Paris


Developers have selected a design by an American architect for a new building nearly as tall as the Eiffel Tower and powered partly by the wind, reports MSNBC.


Dubbed the Lighthouse, the 984-foot-high skyscraper will be designed by Thom Mayne and erected at La Defense, a complex of office towers in a business district west of Paris where many of France’s major corporations are headquartered.


Mayne’s design shows a building “curving asymmetrically upward, topped by a crown of spiky antennae.” It’s being billed as a “green” building, as the wind turbines on the roof will power the building’s heating and cooling system for a part of the year. A retractable outer layer will reduce the heat from sunlight through the windows in summer.
Set for completion in 2012 and reported to cost upwards of $1 billion, the building will be shorter than the 1,062-foot Eiffel Tower but significantly taller than Paris’ highest office building, the 688-foot Montparnasse Tower.

Innovative Architecture of the HSB Turning Torso







Turning Torso


Santiago Calatrava, one the world's most forward thinking and experimental architects today, has put Sweden on the architectural map. In Malmö, Calatrava designed the HSB Turning Torso, a tower comprised of business and meeting space interspersed with mostly residential apartments. Consisting of nine twisting steel cubes, the gleaming building (based on a sculpture of the same name) spirals into the air offering unparalleled views for all it's residents, whether they prefer the waterfront or the surrounding city. Motion, of course, is the chief inspiration of the Turning Torso; and one cannot help but view the structure as an almost living thing that is freely moving in the open air. Moreover, the aforementioned sculpture on which the building is based was, in fact, also designed by Calatrava. Both, art piece and structure, are influenced by the twisting human body, an image that breaths further life into the building.

Turning Torso 2

Given the much needed trend of the growing concern with environmentally sound architecture, Calatrava designed the building with conservation in mind. The tower is powered by 100% locally produced renewable energy through a wind-power park and solar cells, and waste is managed through individual organic waste grinders that sends the material to a decomposition plant where it is turned into "biogas" (which is basically a refined substance derived from organic waste). These biogas can then be used instead of natural gas for things such as gas cookers, fuel for vehicles, or production of district heating.

Turning Torso 3

It's hard to look at the Turning Torso and not question its construction, which was so complicated it was featured on Discovery Channel's "Extreme Engineering." Constructed of almost 40 very large "steel cigars," the curvature of the building was the most obvious challenge. The façade is made of 2,800 aluminum panels and 2,250 glass windows that each merit special fabrication in order to make the building as structurally sound as possible. In order to follow the turning of the building, each panel leans either inward (on the west side of the building) or outward (on the east side) from a range of 0 to 7 degrees. And, if window washing is your concern, don't fret. Included in the rent is a window washing service that uses a state of the art crane to keep the outside nicely polished. What a deal.

Calatrava's next project is the Fordham Spire in Chicago which is set to become the tallest structure in the world. And, if the Turning Torso is any indication, Chicago's downtown image, like Malmö, should receive a refreshing burst of revitalization that will once again showcase the astonishing talent of Santiago Calatrava.

Green skyscraper, Paris





Green skyscraper will have 'steel-like' concrete skin
Paris-based architect Jacques Ferrier was at the AIA Show in San Antonio earlier this month to show off his latest concept for a “green” mixed-use skyscraper, called Hypergreen.

The design, which was recently submitted for a project competition in Paris, incorporates a curving lattice façade made of ultra-high-performance concrete that will act as the building’s primary structural system. The thin, prefabricated concrete members will free the interior structure from any wind-bracing functions, reducing the number of columns required to support the floor plates.






















Hypergreen building facts
Height: 246 meters
Green features:
* Geothermal heat pumps
* Photovoltaic panels
* Wind turbines
* Earth cooling tubes
* Vegetated sky lobbies
* Roof garden
* Rainwater recovery
* Highly flexible and adaptable floor plates
* Deconstructability
Structural system:
* High-performance concrete exoskeleton made of Ductal from Lafarge
* Interior frame structure built with precast reinforced concrete
