World’s Tallest Buildings

By James White

The formation of tall buildings dates back to the days of the Great Pyramid, where three pyramids were built in the honor of the pharaohs. These pyramids remained the largest structures in the world and, controversially, some of the oddest shaped structures in the world. However, since the 1800’s skyscrapers were being built around the world. As one structure was built in a country, another was already trying to surpass it. In lieu of this, many towers have been built and have surpassed the Great Pyramids by exceptional rates.

The Great Pyramid of Giza was built in 2550 B.C. in El Giza, Egypt in honor of the pharaoh Khufu and his three wives, which were all placed inside the pyramid. Sectioned out, the pyramid has a “King’s room” where the pharaoh was left to lie with his riches. There is also subsections for his wives, where they all have their own rooms known as the “Queen’s Room” which holds their remains and riches. The construction of the Great Pyramid of Giza took years of hard work and would accumulate approximately $5 billion worth of work today. The pyramid stands the tallest of the three, standing around 455 feet tall.

Setting all new limits, America set all new standards for the tallest building in the world. The Empire State Building in New York City was constructed in 1931. The Empire State Building stands 1,451-feet tall as the tallest building in NYC right now, since the destruction of the twin towers in 2001. However, the construction of the One World Trade Center, the Empire State Building will once again be surpassed in New York City. The One World Trade Center will stand 1,792 feet tall from bottom to tip and will be opened in early 2014.

The largest building in America until the One World Trade Center opens, however, is the Willis Tower, which was built in 1973, and stands 1,729 feet. The Willis Tower is located in Chicago, Illinois and remained the tallest building in the world until 2010 when it was surpassed by the Burj Khalifia in Dubai.

The Burj Khalifia featured in Dubai, United Arab Emirates stands an impressive 2,717 feet tall and will remain the largest building until the Sky City, in China is completed in 2014. Opened in 2010, the original construction of the Burj Khalifia was not intended to stand as tall. However, as construction came to a closing, the architect did not feel as though the 2,300-foot tall building was shaped correctly at the top. Scientifically, structures are more unsound if they do not tip off at the top, which can cause the foundation to lose sturdiness. The overall structure was changed 400 feet to make a more “pointed” top opposed to a leveled, rounded top

These buildings remain some of the most iconic buildings in the world. However, not just due to their height, but also because of their structural designs which all differentiate greatly. Even so, they all contain one similar attribute – the peaks. From the triangle shape of the Great Pyramid to the updated structure of the Burj Khalifia, it is common for larger buildings to “tipoff” at the top. Structurally and scientifically, these buildings rely on their structural designs to avoid an unsteady foundation – which can be the cause of it falling from harsh winds to a natural disaster. The scientific aspect of architecture creates an elaborate design that even the Egyptians knew of many years before modern science identified it.

Prospected that taller buildings will be built throughout the upcoming years, after the completion of the Sky City in China, it is foreseeable that the tip of each building will premiere the same silhouette, favoring that of a triangle. Science has forged a way for us to make tall structures sound without much repercussions.

Ancient Egyptian Astronomy at the Osireion

The ancient Egyptians were not morbid, a statement which may seem odd when considering their many burial chambers, tombs, mortuary temples and other similar sites that remain standing in present-day Egypt. It was rather that they celebrated life so much they wanted to ensure all earthly pleasures could be enjoyed continuously in the afterlife. They believed that they could do this by elaborately depicting everyday scenes, probably very much idealized, on walls and ceilings leading up to and surrounding their place of interment. Included in these portrayals are tantalizing representations of the ancient Egyptian night sky, which give us some insight of how they interpreted the celestial sphere and the range of objects within it. Many tombs and temples have simple stars on their ceilings, but a rare few contain more complex information. Such is the Osireion.

The Osireion is a symbolic tomb for Osiris, one of the most famous ancient Egyptian gods, and is located at Abydos, a two-hour drive north of Luxor. It was discovered at the turn of the twentieth century by Flinders Petrie and Margaret Murray, and while there is disagreement of the exact age of construction it is likely to be in the late New Kingdom (1300-1100 BC). It resembles the earlier Valley of the Kings’ tombs; the original entrance is through a long sloping corridor (see Picture 1) that, via two small chambers and a sharp right-angled turn, eventually brings you to the main pillared hall. One very unusual aspect of this tomb, however, is that this hall has a moat around its outer edges. The original design used the natural level of the water table to ensure that this moat was filled, with the water representing the primeval waters of creation. Access to the hall’s floor and symbolic burial chamber at the very end of the tomb is made a little trickier than in most tombs because of this water.

There are two ceilings of astronomical interest in the Osireion. The one found in the burial chamber is perhaps the most astronomically significant ceiling discovered so far for this ancient civilization. It contains not only information about daily and annual celestial motions, but also provides specific details of the heliacal rising and disappearance dates for some of their most highly revered stars. And, if that was not enough, there are instructions on how to make a sundial. The other ceiling is a fragment of a “diagonal star table” (or DST) found on the soffit of a lintel in the corridor between the two outer chambers. A favoured interpretation by scholars is that DSTs are representations of a particular band of stars across the sky, and how this band would have appeared to move over the course of the ancient Egyptian year. The Osireion DST is the only one of about 25 DSTs that is not found on the underside of a coffin lid.

If you visit the Osireion today, you can see that the thousands of years since it was built have taken their toll on this monument. The roof of the outer chambers and main hall have collapsed, exposing the rooms so that visitors can obtain an impressive view inside the tomb (see Picture 2) while still appreciating the surrounding vista of a nearby ancient temple on one side and the desert and its sandstone hills on the other. A modern-day wooden staircase leads from the surrounding walls directly to the bottom of the pillared hall. The mysterious moat, however, has the potential to cause problems for visitors – especially if the water table has risen and blocks access to the tomb, as it had on the author’s visit (May 2013).

The site, even if partially submerged, is still impressive. A visit here would definitely also include seeing the Seti I Temple. This temple is most famous for the “Abydos King List”, a chronological list of many pharaohs’ cartouches that is of calendrical significance because it helps determine the chronology of the whole civilization. It also contains a single stone slab with the only remains of an astronomical ceiling. On the same day, you could also visit the relatively nearby Temple of Hathor at Dendera, which exhibits a number of astronomical ceilings, including a replica of the Dendera Zodiac (a replica because the original is now housed in the Louvre).

There are a wealth of fascinating astronomy-related artifacts to be seen all around Egypt, from Cairo all along the Nile to Aswan, and this article highlights just one of the author’s favourites.
