We can’t know all the thoughts that coursed through William Penn’s mind when he chose Philadelphia as the name for his new city, tucked onto the peninsula between the Delaware River and the Schuylkill.

The name he gave his city combined the Greek words for love (phileo) and brother (adelphos), setting up the enduring civic nickname: the City of Brotherly Love.

Philadelphia is Pennsylvania’s largest city, is notable for its rich history, on display at the Liberty Bell, Independence Hall (where the Declaration of Independence and Constitution were signed) and other American Revolutionary sites. Also iconic are the steps of the Philadelphia Museum of Art, immortalized by Sylvester Stallone’s triumphant run in the film "Rocky."
