Windsor Terrace straddles the line between the original Dutch Colonial Brooklyn towns of Brooklyn and Flatbush, as can be seen from its street grid that is bent approximately northeast-southwest along present-day Terrace Place [REF].
Even though Prospect Park W takes the place of 9th Avenue in the Windsor Terrace grid, it actually continues with the "Prospect Park W" name south of Prospect Park SW, which continues Prospect Park's boundary southeastward, and 15th Street.
