Unfortunately you can't tour it, but it's certainly worth ogling. At the intersection of Wall and Broad streets, the exchange is impossible to miss. The neoclassical building, designed by architect George B. Post, opened on April 22, 1903. It has six Corinthian columns supporting a pediment with a sculpture titled Integrity Protecting the Works of Man, featuring a tribute to the then-sources of American prosperity: Agriculture and Mining to the left of Integrity; Science, Industry, and Invention to the right. The Exchange was one of the world's first air-conditioned buildings.
