Wall Street is the symbolic and geographic center of American capitalism. Geographically, Wall Street is the center of Manhattan's financial district. It runs east/west for eight blocks from Broadway to South Street. The Street ran along a physical wall built by Dutch settlers when New York was still a Dutch Colony.
