While you may not sail the great blue seas, you can explore the history they played in Philadelphia’s development at the Independence Seaport Museum. A museum dedicated to the maritime history of Philadelphia, the Delaware Valley and Pennsylvania, the Independence Seaport Museum is suitably located along Penn’s Landing, the historic site where William Penn first docked when he arrived in America.
Planned by William Penn during the late 17th century, Franklin Square is one of the five original open-space parks in Philadelphia. According to local legend, this park is where Benjamin Franklin conducted his famous "kite and key" lightening experiment. This square is dedicated to outdoor fun, with a carousel, mini golf course, fountain and playground located on the premises.
