The Gateway Arch has graced the St. Louis riverfront since October 28, 1965—long enough that locals and visitors might struggle to picture the city skyline without the striking silver monument. But back in the late 1940s, plans for the architectural marvel went head-to-head with more than 150 other designs to win out as the cornerstone of the future Jefferson National Expansion Memorial.
The monument along the banks of the Mississippi River was established in the 1930s to honor Thomas Jefferson, the Louisiana Purchase and the pioneers who expanded the United States westward, but its development took time. In 1947, the Jefferson National Expansion Memorial Association launched a national design competition for the site. It marked the first major design competition following World War II and offered the sizable first prize of $40,000, drawing some of architecture’s biggest names. Furniture designers Charles and Ray Eames, modernist Walter Gropius and Minoru Yamasaki, the future designer of the World Trade Center, all threw their hats in the ring.
Names mattered little, however, as the judges reviewed 172 conceptual drawings marked only with entry numbers to keep the focus on the merits of the individual plans, not the people who submitted them. After naming five semifinalists in September 1947, the jury selected the winning design—a soaring stainless steel arch designed by a relatively unknown architect—in February 1948. Had the jury selected any of these following entries over the Gateway Arch, however, the Jefferson National Expansion Memorial would look considerably different today.
