The park name is a play on the name of Stuyvesant’s sprawling farm, or Bouwerie, which once encompassed this location: Petersfield.
Of course, Stuyvesant graces a ton of other landmarks in the area: Stuyvesant Town, Stuyvesant High School (the original building), and Stuyvesant Square.
Peter’s Field also commemorates another famous Peter who lived in the neighborhood: Peter Cooper. He’s the Kips Bay glue manufacturer, founder of Cooper Union in 1859, and namesake of Peter Cooper Village.
Ah, but the little park pays homage to more Peters. Cast concrete plaques put up in the 1990s on the Second Avenue side honor Peter Rabbit, Peter Pan, Peter Piper, Peter Parker, and other fictional characters who share Stuyvesant and Cooper’s name.
