Local legend maintains that Franklin Square is where Benjamin Franklin conducted his famous, though misunderstood, "kite and key" experiment in 1752. However, it would have been unlikely for Franklin to fly a kite near a cemetery, and not all that far from possible observers from town. The legend is memorialized in Isamu Noguchi’s "Bolt of Lightning... A Memorial to Benjamin Franklin", a 101-foot tall, 60-ton stainless steel sculpture commissioned by the Fairmount Park Art Association and costing $850,000. It was erected in 1984 in Monument Plaza at the base of the Ben Franklin Bridge, facing the Square across 6th Street, a location personally chosen by Noguchi.
