The Gateway Arch, located in St Louis, Missouri, is considered to be one of the most iconic structures in the United States. Built to commemorate the Louisiana Purchase and westward expansion, the arch stands as a symbol of the nation’s pioneering spirit and a reminder of the history of the area. The Gateway Arch is a 630-foot stainless steel structure that stands tall along the banks of the Mississippi River in downtown St. Louis. It is the tallest arch in the world and is a popular tourist attraction, drawing thousands of visitors annually.
The idea of building an arch to commemorate the Louisiana Purchase and westward expansion was first proposed in 1933 by civic leader Luther Ely Smith. Smith’s vision was to create a structure that would represent the courage and determination of the early settlers. Smith’s proposal was met with enthusiasm by the city of St. Louis and a design competition was held to choose a design for the arch. The winner of the competition was Eero Saarinen, whose design was chosen for its graceful curves and modernist aesthetic.
Construction of the arch began in February 1963 and took two and a half years to complete. The arch was built using a system of prefabricated stainless steel segments that were welded together on site. The arch is composed of two legs that are connected at the top by a curved catenary arch. The legs are made up of four triangular sections that are connected by a series of vertical and horizontal struts. The arch is supported by a network of cables and concrete foundations that extend deep into the ground.
The arch is also home to the Museum of Westward Expansion, which is located beneath the arch. The museum houses exhibits about the history of the area, including artifacts from the Louisiana Purchase and westward expansion. Visitors may also take a tram ride to the top of the arch, where they can enjoy a breathtaking view of the city.
