The historical boundaries of Park Slope swelled for the first time in 39 years today, when the Landmarks Preservation Commission voted to approve an expansion of the neighborhood's Historic District, making it one of the largest historic districts in America. Owners of 580 buildings will see their property values rise, in a new zone stretching from approximately 7th Street to 15th Street (including the 7th Avenue frontage), 7th Avenue to 8th Avenue, and along 15th Street from 8th Avenue to Prospect Park West, including the western side of Bartel Pritchard Square—all the way to 16th Street. See the map below.

During our time in Windsor Terrace the locals drilled it into our heads that Park Slope ends at 15th Street, so this kind of turns our worldview upside down. What's next, Terrace Bagel starts bragging about the best bagels in Park Slope? Farrell's bar opens a special stroller section for Mommy Happy Hour? LOCALLY SOURCED ORGANIC ARUGALA AT THE KEY FOOD ON PROSPECT AVENUE?

Reached for comment, Gothamist publisher and Park Slope native Jake Dobkin tells us, "Windsor Terrace's days are numbered—soon it'll just be called Park Slope southeast or whatever. While the swells by the Park are busy patting themselves on the back, the proletariat below 7th Avenue still suffers, as the capitalist exploiter class gentrifies their blocks with roof additions and non-historically correct doorknob hardware. The sturdiest 19th century iron garden fencing will not keep you safe from our rage—expect us!" (At press time, Dobkin was en route to his anarchist-syndicalist commune in Brooklyn Heights and was unable to provide further comment.)

Anyway, the district extension also includes the former Ansonia Clock Works factory, once the world's largest clock manufacturer, as well as homes built for its workers. In a statement, Councilmember Brad Lander said, "These are some of the most beautiful streets in New York and, with today’s vote, we know they will be enjoyed by generations to come."

And this is only the beginning—the Park Slope Civic Council is pushing for a much larger Park Slope Historic District that would include hundreds of additional buildings above 5th Avenue. Today, 5th Avenue, tomorrow, who knows, maybe Red Hook? Park Slope Über Alles! Don't get too comfortable, Gowanus—or "West Slope,"as we like to call it.
