|postcard of St Louis' Gateway Memorial Arch|
It was designed by Finnish American architect Eero Saarinen and structural engineer Hannskarl Bandel, who won a design contest for the Arch, and was completed in 1965. At 630 feet (192 meters), it is the tallest man-made monument in the USA. It's height is equivalent to about 63 floors, if every floor is the average 10 feet high! If you dare, there is a tram system that can take up to 6,400 visitors to the observation room at the top every day when both trams are working in the summer.
Some interesting facts about the Gateway Arch from the National Park Service website:
Is the Arch moving?
The Arch is designed to sway as much as 18 inches, and can withstand an earthquake, however under normal conditions the Arch does not sway. It takes a 50-mile an hour wind to move the top 1 1/2 inches each side of center.
OK, I'm not sure I'd want to be up there in strong winds or nasty weather...Has the Arch been hit by lightning?
The Arch has a series of lightning rods on the top which are grounded directly into bedrock, with a perfectly insulated interior. It is able to withstand hundreds of lightning bolts which hit it each year.
The steel Arch is the centerpiece of the Jefferson National Expansion Memorial, which includes a 91-acre (36.8-hectare) park along the Mississippi River park, the Old Courthouse and the Museum of Westward Expansion.
Lookeee, I found this interesting article on the Arch from 1964: Tallest U.S. Monument (Popular Science, April 1964) via Google Books. It details the construction and has a nice infographic on the tram to the top of the monument.
Something else interesting I learned while researching the Arch, St Louis city is in Missouri but the Great St Louis metropolitan area straddles 2 states: Missouri and Illinois.
