[3] Prior to the 1800s the city developed along the Delaware River, leaving the area around Logan Square as untouched forest through the American Revolution.

[8] It was designed by Jacques Gréber, a French landscape architect who converted Logan Square into a circle similar to the oval of the Place de la Concorde in Paris.

Among the sites in its immediate vicinity are the Swann Memorial Fountain at the center of the circle, Parkway Central Library, the former Philadelphia Family Court Building, the Academy of Natural Sciences, the Franklin Institute, Moore College of Art and Design, the Roman Catholic Cathedral-Basilica of Sts.

[10] In early 2005, the Pennsylvania Horticultural Society (PHS) began efforts to clean up and redevelop the park to make it more accessible and inviting to pedestrians.

They were replaced with similar trees grown especially for Logan Square at Longwood Gardens as part of a larger plan to improve the space.
