The monument to the design of the monument was won in 1948 by American architect Eero Saarin, who did not live to finish the construction.
The Entrance Arch, a high symbolic gate made of shiny stainless steel, commemorates the role of St. Louis as a "gateway to the West" in pioneering times.
It rises 192 m up and has the shape of a rainbow, which symbolizes hope for the future and reconciliation between God and humanity. The shape of the rainbow seems to be the most suitable for the monument of thousands of men, women and children who set off with great hopes from the world they knew to populate open spaces in the west. The bow expresses excitement with the enterprise and colossal achievement of the conquest of the Wild West.
Inside the arch there are elevators reaching the portholes high above, from where there is a great view of St. Louis and the Mississippi River. On both legs there are 8 capsules for 5 passengers reaching the summit in four minutes.
At the top there is a viewing terrace that can seat 160 people, on a clear day you can see areas distant 48 kilometers.
The geometrical form of the structure was determined by means of mathematical equations passed to Saarinen by Hannskar Bandel.
Despite the optical illusion, the Gateway Arch is exactly as wide (192 meters) as it is tall (192 meters).
The foundations of the arch are sunk 18 meters in the ground.
The structure is made of steel and concrete, its outer shell is made of stainless steel. The whole weighs 38 898 tons, of which concrete weighs 23 570 tons, internal structural steel weighs 1957 tons, and external stainless steel panels weigh 804 tons.
The structure has been designed to withstand strong winds and earthquakes. Its deviation at the top reaches 2.5 centimeters in a wind of 32 km / h and the maximum deviation foreseen is 46 cm.
Gateway Arch is one of the most visited tourist attractions in the world. Every year, more than four million tourists visit it, of which about a million travels to the top.
