The Gateway Arch in St. Louis, Missouri, is a 630-foot stainless steel monument designed by Eero Saarinen and completed in 1965, symbolizing the city’s role as the “Gateway to the West.” As the tallest arch in the world, it celebrates America’s westward expansion with its bold, modern design. Visitors can ride a tram to the top for stunning views of the Mississippi River and St. Louis. #architecture #gatewayarch #usa #arch | World architecture inspiration
