The Treaty Elm, [[Philadelphia]], [[Pennsylvania]]. In what is now [[Penn Treaty Park]], the founder of [[Pennsylvania]], [[William Penn]], is said to have entered into a treaty of peace in 1683 with the [[indigenous peoples of the Americas|native]] [[Lenape]] Turtle Clan under a picturesque elm tree immortalized in a painting by [[Benjamin West]]. West made the tree, already a local landmark, famous by incorporating it into his painting after hearing legends (of unknown veracity) about the tree being the location of the treaty. No documentary evidence exists of any treaty Penn signed beneath a particular tree. On March 6, 1810 a great storm blew the tree down. Measurements taken at the time showed it to have a circumference of {{convert|24|ft|m}}, and its age was estimated to be 280 years. Wood from the tree was made into furniture, canes, walking sticks and various trinkets that Philadelphians kept as relics.<ref>{{cite web|url=http://www.haverford.edu/arboretum/collections/penn_treaty_elm.php|title=Penn Treaty Elm|publisher=Haverford College Arboretum|access-date=December 28, 2014|url-status=dead|archive-url=https://web.archive.org/web/20141227191052/http://www.haverford.edu/arboretum/collections/penn_treaty_elm.php|archive-date=December 27, 2014}}</ref>
