Book excerpt: St. Louis' Gateway Arch rivals the monuments of the world in its simplicity, scale, elegance, and symbolism. The shimmering, stainless-steel ribbon forms a catenary arch 630 feet tall and 630 feet across at its base. Its design amazed the civic leaders determined to construct a great monument on the St. Louis riverfront. When it was completed, it wowed not just St. Louisans, not just Americans, but also visitors from around the world. Its sleek geometric design and engineering was a creation of the Space Age, but the Arch was a monument to America's frontier heritage. The Gateway Arch commemorated St. Louis' riverfront as the Gateway to the West. With a selection of fine historic images from her best-selling book Historic Photos of the Gateway Arch, NiNi Harris provides a valuable and revealing historical retrospective on the design and construction of this world-famous landmark. Remembering the Gateway Arch chronicles the St. Louis riverfront from its days as a fur-trading post, to the creation of the Arch. From clearing the site to welding the first section into place, to the breathtaking moment of inserting the keystone--the photos tell the story.
