Humans create a lot of impressive buildings. In the ancient
world, it was the pyramids. Then there were the cathedrals of the
Middle Ages. Today, we have skyscrapers. Skyscrapers really
began with the Empire State Building, which opened May 1, 1931. At
1,250 feet, it was the world's tallest building until 1954.
Surprisingly, it is still in the top 20. There are now countless
skyscrapers around the world. Dozens more are under construction.
Plus, new advancements are being made all the time.
Skyscrapers are being designed to reach unimaginable heights. Others
have unique and previously unseen shapes.
(Height in meters, NOT feet)
Due to the disagreements over how to measure height and classify
structures, engineers have created various definitions for
categories of buildings and other structures. One measure
includes the absolute height of a building, another includes only
and other permanent architectural features, but not
antennas. The tradition of including the spire on top of a
building and not including the antenna dates back to the rivalry
Chrysler Building and
40 Wall Street. A modern-day example is that the antenna on top
of Willis Tower (formerly Sears Tower) is not considered part of its
architectural height, while the spires on top of the Petronas Twin
Towers are counted.
