Gateway Arch

The Gateway Arch, located at Memorial Drive, St Louis, Missouri, was designed by the Finnish/American architect and industrial designer Eero Saarinen.
Built as a monument to the westward expansion of the United States, the arch typifies the pioneer spirit of the men and women who won the West and those of a later day to strive on other frontiers. The Arch has become the iconic image of St. Louis, appearing in many parts of city culture.
It stands at 192 meters (630 ft) high, making it the tallest arch ever built and the tallest monument built by the United States of America. The arch’s width is the same 192 meters as its span.
The Gateway Arch is fabricated from 6.3mm thick grade 304 stainless steel. The stainless steel is finished in No. 3 Finish – this finish is obtained with a ground unidirectional 80 to 100–grit abrasive. The stainless steel covering the arch weighs 804 tons.
