Experience the magic of the holiday season at Winter in Franklin Square presented by Citizens, featuring the Electrical Spectacle Light Show presented by PECO from November 21 through February 23, a spectacular light show that drapes 50,000 twinkling lights across the park’s fountain and connects to a 12-foot tall kite, in an ode to Benjamin Franklin’s famous experiment. Every half hour, an alternate light show plays to the sounds of holiday classics.

New this year, Winter in Franklin Square features new songs in the Electrical Spectacle Light Show; outdoor fire pits and beautiful indoor heated tents with adult and hot beverages and seasonal food at Franklin’s Winter View; and Center City’s only miniature golf course both daytime and evenings transformed into Chilly Philly Mini Golf presented by IBEW Local 98.
