Which of these landmarks is the same height and width?
Taj Mahal
Gateway Arch
Mount Rushmore
Great Pyramid of Giza
The Gateway Arch in St. Louis, Missouri, is unique among landmarks because it is both 630 feet tall and 630 feet wide, making it a perfect, symmetrical structure. Designed by Eero Saarinen and completed in 1965, the Arch was built as a monument to the westward expansion of the United States. Its shape, called a weighted catenary arch, creates an elegant and sweeping design that appears to reach upward while curving gracefully. This iconic structure is the tallest arch in the world and the tallest man-made monument in the Western Hemisphere.
Correct Answer: Gateway Arch
