A stroll through the small park will take you down tree-lined walkways and to the park’s main monument, the Tomb of the Unknown Soldier of the Revolutionary War, which features an eternal flame. Forming part of Independence National Historical Park, Washington Square is often visited as part of history-focused tours of Philadelphia along with nearby Independence Hall, the Liberty Bell Center, and other sites connected to the Revolutionary War and the founding of the US government. Biking, walking, and Segway tours of the landmark-packed Old City often stop here.
Washington Square also served as a burial site for the victims of the Revolutionary War and the 18th-century yellow fever epidemic, as well as for Philadelphia’s poor. For this reason, it’s often visited as part of ghost tours of the city.
