The tallest man-made monument in USA, the Gateway Arch has a height of 630 feet. The tallest accessible structure in Missouri, it is the Jefferson National Expansion Memorial’s centrepiece.  The largest architectural structure created as a flattened or weighted catenary arch, it was designed by structural engineer Hannskarl Bandel and Eero Saarinen, a Finnish American architect. Located on the Mississippi River’s west bank, the arch is a spectacular sight, especially in the evening.
