Curtis Bay underwent a radical transformation and evolved and grew quite differently from more "Americanized" residential suburb of nearby Brooklyn, with much less industrial and port / railroad development. The newly acquired Polish Home Hall soon functioned as a social, educational, and political center for Curtis Bay's growing expanding Polish community (along with several other East European peoples attracted to the same community of neighboring Slavic immigrants, with the second largest numbers of Poles and others in a Baltimore neighborhood besides near Fells Point and adjacent Canton or Highlandtown communities, further northeast across the Patapsco River / Baltimore Harbor in the southeast part of the city, which remained heavily ethnic Polish into the 1970s. After 102 years of over a century of little appreciation and recognition, the Polish Home Hall in Curtis Bay was listed on the National Register of Historic Places, maintained by the National Park Service of the U.S. Department of the Interior in 2007.
