This is the Gateway Arch located in St. Louis, Missouri and it was designed by Eero Saarinen in 1947. I never traveled anywhere growing up besides going to school and home, but I decided to go on a road trip a few years ago. During my trip, I saw this arch while driving and it was my first encounter with architecture besides common buildings. I thought it was so fascinating how tall it was and wondered how it could even support itself. To this day, it’s still one of my favorite structures to see when I’m traveling.
