Though it's historically likely that Penn did, in fact, sign a treaty pledging perpetual peace with the Lenni-Lenape, the details of this scene are apocryphal. The elm on the shore of the Delaware under which the meeting was purportedly held blew down in a storm in 1810, and a small obelisk was erected on the spot to commemorate the treaty in 1827. The land is now Penn Treaty Park, a small park in Fishtown overlooking the river and the Benjamin Franklin Bridge.
