George Bridport’s 1816 design led to two hundred years of various improvements, planting changes, and redesigns, but through that time, the core function and design of Washington Square has remained. Through all designs, Washington Square has maintained its diagonal walks, central feature, canopy trees, grass, and space for walking and sitting. Prominent designs from 1816 to 2022 are: George Bridport’s 1816 circular design, William F. Dixey’s 1881 geometric design, Olmsted Brother’s 1913 rotated design, Edwin Brumbaugh & Thomas Sears 1953 memorial & fountain design, and Fairmount Park Commission & Delta Group 1990s renovations. Presently, Washington Square maintains most design features from Brumbaugh’s 1953 design and various elements of each design since 1816.
