How do the St.Louis arch represent diversity in America?

I don't know that it was built to represent diversity. It was meant to immortalize westward expansion. As travelers moved to the west, St. Louis became pretty much of a melting pot. What had started out as a French fur trading station, grew into a more industrialized community. As the city enlarged, there were areas for German, Italian and Irish immigrants. During the civil war, we were a divided city and there were some stops on the underground railroad in our community and the African American population began to grow. So I guess you could say that as people began moving across the country, cities to the west of the Mississippi became more diverse.How do the St.Louis arch represent diversity in America?
It was built as a monument to the western expansion of the United States. I've briefly "googled" and searched to find some representations of diversity regarding the "arch" but have come up with little to nothing. Most diversitive articles were in regards to a community food drive under the arch, or a local job fair at the river front area under it and nearby. I suggest that you try more research on your own. Try Google and Wikipedia, and follow the links and results from those search points.How do the St.Louis arch represent diversity in America?
The city's many 19th-century German breweries shaped beer in the United States, most notably Anheuser-Busch, Falstaff Brewing Corporation, and Lemp Brewery. With its French past and numerous Catholic immigrants in the 19th and 20th centuries, St. Louis is one of the largest centers of Roman Catholicism in the United States. Many African Americans moved north to the city in the early 20th century during the Great Migration. The arrival of African Americans from the South helped bring about the St. Louis styles of blues, ragtime, and jazz.
