IN THE SHADOW OF THE ARCH
If you're anywhere near downtown St. Louis,
you're close to the shadow of the
St. Louis Gateway Arch.
Completed in 1965, it has become
the symbol of our city.
Designed by Eero Saarinen
and constructed of stainless steel,
the arch stands 630-feet high
and 630-feet wide . . .
which makes it the strongest possible
architectural structure, a catenary arch*.
*Hang a chain whose width is the same
as its height, freeze it, flip it over,
and you have a catenary arch.
The St. Louis Gateway Arch
symbolizes the Jefferson National
Expansion, west of the Mississippi.
(There are little elevators inside
which can take you to the top,
for a magnificent view.)
