This is Gracie Mansion the official residence of the Mayor of New York, although our current mayor chooses to live in his own townhouse. It is located on the Upper East Side of Manhattan within Carl Schurz Park, along the East River. We passed by it on a circle line boat tour I was on so I only got a passing glimpse as we went by. Maybe I'll go back in the spring time and have a look at it close up. You can read more about it at http://www.nyc.gov/.
