In this amazing capture, we see the famous Gateway Arch monument in St. Louis, Missouri, enshrouded in low passing clouds. The image was submitted to Reddit by user llamapen who says his father took the photograph from the 40th floor of One Metropolitan Square, a skyscraper in downtown St. Louis. At 180.7 m (593 ft) it is the tallest building in the city and the second tallest building in Missouri.
The Gateway Arch is a 630-foot (192 m) monument built in the form of a flattened catenary arch. It is the tallest man-made monument in the United States and the world’s tallest arch. Built as a monument to the westward expansion of the United States, it is the centerpiece of the Jefferson National Expansion Memorial and a famous symbol of St. Louis. [Source]
The Gateway Arch was designed by Finnish-American architect Eero Saarinen and German-American structural engineer Hannskarl Bandel in 1947. The monument opened to the public on June 10, 1967. [Source]
