The Sears Tower is as tall as 1,454 feet, and even
taller (1707 ft.) when you include its twin antennas, which are each
over two hundred feet tall. The Sears Tower is a massive 110 stories tall.
The Sears Tower is located on Wacker Drive in Chicago, Illinois. This
was a smart place to construct it, because many people in the area were
in need of office space.
When the Sears Tower was finished being built, it was filled with about
twelve thousand workers. This massive tower was designed by the
architecture firm of Skidmore,
Owings, and Merrill.
This tower was completed in 1973. After this building was done being
constructed the world had a new tallest building. The Sears Tower has a
steel frame which is surrounded in bronze tinted glass and stainless
aluminum. The foundation consists of a one- hundred foot deep hole, and
is surrounded by two- hundred circular caissons around the foundation.

The Tribune Tower is on 435 N. Michigan Avenue,
just north of
the Chicago River. The Tribune Tower was built from
1922-1925. The architects of the Tribune Tower
were Raymond M. Hood and John Mead Howells. The Chicago Tribune
newspaper held a contest in
1922 to design the Tribune Tower. They wanted the world's most
beautiful office building. Raymond M. Hood and John Mead Howells were
the winners of the contest. The Tribune Tower is important because the offices
of the Chicago Tribune newspaper are located there. There are over 120 stones in the Tribune Tower
taken from other sites and structures. Some of them are from Bunker
Hill, Mark Twain's "Injun Joe Cave", the Parthenon, and the
Taj Mahal.

The Water Tower was built in 1869 and it is
on
North Michigan Ave., but it looks like it's on Chicago Ave. W.W.
Boyington, a great architect, designed the Water Tower. He also
designed how it would pump water from Lake Michigan. The Water Tower
is made out of limestone. The pipes are very secure, being some of the most secure pipes in the world. They are
covered heavily with limestone, too. Before
the Water Tower, Chicago's water was really bad. Chicago pumped its
water from the Chicago River which was also the city's sewer. Then,
W.W. Boyington designed how the Water Tower would pump cleaner water
from Lake Michigan to the city. The Water
Tower was important because Chicago's drinking water was very bad
until it (and the Pumping Station across the street) was built to
bring in water from Lake Michigan. Now, the Water Tower is important
because it is one of a very few buildings in this part of Chicago to
make it through the Chicago Fire, which makes it a historical
landmark.
This
skyscraper is located on North Michigan
Avenue,
near the Water Tower.
The John Hancock Center was designed by Bruce Graham, a
well known architect who is part of the Skidmore, Owings, and Merrill
architecture firm. This was one of his first and most popular
buildings. Graham's influence for designing this skyscraper was to
make it fit in with the surroundings of the site, because it was going
to be built on North Michigan Avenue, a place where many shops and
businesses were located. The John Hancock Center was completed in
1970. The first
five stories are stores, six through twelve are for parking, 13
through 41 are offices, 44 through 92 are condos, and 93 through 100
are for television facilities, an observatory, a restaurant, and
mechanical uses. The John Hancock Center is 344 meters tall, and has
one hundred stories. The building is able to support these one hundred
stories because it tapers from top to bottom.


Marina
City is located at 300 North State Street, between State and Dearborn
streets. It is a semi-circular building that was built in 1959. Many
people say the building resembles corncobs. The amount of money to
construct this was $36,000,000.This is a modern style building and
takes up only 3 acres.
Marina City was designed by
Bertrand Goldberg. He was born in 1913 and studied at Harvard, as well
as Illinois Institute of Technology. He also worked with Ludwig
Mies van der Rohe. Marina City has four hundred and fifty
apartments in each of the towers. The apartments are in the top
portion of the building. The parking portion of the building can accommodate
450 automobiles. Marina City provides many Chicagoans with a place to live and park
their car. It also has restaurants, theaters, and a place to park
boats. Marina City is a beautiful part of Chicago's skyline.


The Monadnock Building is located at 53 West Jackson
Boulevard, the same street as the Chicago
Board of Trade. The north part of the
Monadnock Building was designed by Burnham
and Root,
two very famous Chicago architects. The south half was designed
by Holabird
and Roche, who are also famous Chicago
architects. It took from 1889 until 1891 to build
the Monadnock. The north part was finished first, then the south half
was built later. The Monadnock
Building
is
important because the building is part load-bearing wall construction,
and part modern skyscraper with a steel skeleton. It is the tallest
masonry building in Chicago, perhaps the world. The base walls are six
feet thick and they rise to the full 215 foot height of 16 floors. The
style of architecture used in it is called Richardsonian, which is a
style named for the architect H.H. Richardson, who designed the Marshall
Field & Company store on State Street.
