  • Welcome to the beautiful Gateway Arch, also known as the Gateway to the West. The arch

  • is one of the main features of the Jefferson National Expansion Memorial, together with

  • the Old Courthouse and the Museum of Westward Expansion.

  • The memorial area was founded in 1935 in honor of the third US President Thomas Jefferson

  • and the Louisiana Purchase. The Louisiana Purchase was a deal Jefferson made between

  • the United States and France, were France sold much of today's central US to the newly

  • formed country, which effectively more than doubled the size of the United States.

  • While the memorial area has been around since 1935, the planning of the arch didn't begin

  • until after the Second World War. In 1947, a nationwide architectural competition for

  • the design of a new monument was held which was won by the Finnish-American architect

  • Eero Saarinen. His winning entry was what you can see in front of you, the massive Gateway

  • Arch. The construction of the arch itself began

  • later in 1963; it stood finished in 1965 and was opened to the public two years later.

  • During construction, both two legs were built up simultaneously. The base of each leg at

  • ground level had an engineering tolerance of one sixty-fourth of an inch, or else the

  • two legs would not meet at the top, so there was a need of great engineering precision

  • to make it work. The construction team faced another problem when the time came to connect

  • both legs together at the top. The sunlight hitting the south leg caused the metals to

  • expand slightly, which prevented it from aligning precisely with the north leg. In order to

  • solve this problem, the St. Louis Fire Department was called in and sprayed the south leg with

  • water, in which the metal cooled off and the two legs could be united.

  • The arch is made of stainless steel skin covering two carbon steel walls and it stands an impressive

  • 192 meters tall and 192 meters wide. While the outside of the arch is certainly impressive,

  • one shouldn't forget its inside. The interior of the arch is hollow and contains

  • a highly unique transport system which leads to an observation deck at the top. If you

  • look carefully at the top of the arch, you can see the observation deck's small windows.

  • The transport system functions as a combination between an elevator and a tram, with a 40-passenger

  • train made up of eight five-passenger capsules in each leg. Each capsule rotates 155 degrees

  • during the trip to the top of the arch. When the capsule starts out from the lower zone

  • the tracks are overhead but as it goes up the arch the tracks then go beneath the capsule.

  • There is also a conventional elevator reaching halfway up and 1076 stepped stairways for

  • emergency use only. A trip to the top and back takes around 10 minutes and I can highly

  • recommend it, unless you are claustrophobic or very scared of heights of course. The view

  • from the top is great. On a clear day, one can see up to 48 kilometers, from the City

  • of St. Louis to the west across the Mississippi river and southern Illinois with its Native

  • American culture mounds to the east. The entrance to the arch is from the underground

  • visitor center, located directly underneath it. From the visitor center you can move to

  • either base of the arch and enter the tramway through its narrow double doors. Under the

  • arch you will also find the Museum of Westward Expansion. The museum documents man's irrepressible

  • urge to explore and the expansion of the United States. Make sure you don't miss this wonderful

  • museum. Throughout the years, the arch has been the

  • place of several notable stunts and events. More than 10 light aircrafts have successfully

  • flow under the arch and people have been trying to scale and land with parachute on top of

  • it, more or less successfully. Today, the Gateway Arch has become the iconic

  • image of St. Louis and a gateway between western and eastern US. It is also one of the very

  • tallest monuments in the whole US with its mighty 192m. Majestic in its concept, magnificent

  • with its surroundings and unique in its execution, the Gateway Arch is something for history

  • books.
