at the Department of Environmental Protection's new Remsen Avenue maintenance facility
It reads "CITY OF NEW YORK" (took me a while to figure that out), and it's mounted on a wall of the Department of Environmental Protection's new Remsen Avenue maintenance facility. Perhaps the bricks are remnants of the previous DEP facility at this site?
According to Forgotten New York, this structure was completed in 1939, originally served as an ice cream parlor, and is "NYC's one and only building constructed from crosstimbers." It was also thrice firebombed in 1991 after Fillmore Real Estate, under a court order, began showing homes to black and Hispanic customers.
UPDATE: Turns out there's at least one other log cabin in the city: 17 Vulcan Street in Staten Island.
Not interested in talking, but happy to pose for a photo. In case you're wondering, this is where I ran into him.
Is To Create It
