Mile 5: Where St. Michael's Is a Beacon If one of the Towers of Bay Ridge serves as a marker for Mile 4 of the New York City Marathon, then the distinctive, egg-shaped tower of the Church of St. Michael's is a beacon guiding runners up Brooklyn's Fourth Avenue to Mile 5. This stretch is in the Sunset Park neighborbood, but marathoners on Fourth Avenue won't be in its commercial heart. Eighth Avenue is part of Brooklyn's Chinatown, one with more Chinese than the famous one in Manhattan. Once mainly a Cantonese area, immigrants from Fujian province have been arriving in great numbers over the last decade. Sunset Park has another main shopping strip on Fifth Avenue, which caters to a burgeoning Latin American population. Like Bay Ridge, Sunset Park once had a large number of Norwegian immigrants, many of whom worked on the bustling waterfront (interesting history here). One avenue to the left of Fourth is the park for which the neighborhood is named. Running from 41st Street to 44th, and from Fifth Avenue to Sixth, Sunset Park is perched at one of the highest points in Brooklyn and offers spectacular views of New York Harbor. There's St. Michael's. Moving right along.
