The Gateway Arch
The Gateway Arch is in a Midwestern U.S. city. The project’s inception came from civics leader Luther Ely Smith in 1933, who wanted a monument riverside to boost the economy. In 1947, Architect Eero Saarinen designed the arch. Construction started in 1963 and concluded in 1965. As of 2022, the Gateway Arch remains the world’s tallest arch.
