It is bordered by institutions including the Franklin Institute, the Free Library and the Cathedral of SS. Peter and Paul.","why_significant":"The square's present design is tied to Jacques Greber's Benjamin Franklin Parkway of 1918, which kept Logan Square as a focal point of the grand vista. The Swann Fountain by Alexander Stirling Calder and Wilson Eyre and the Shakespeare Memorial by the same collaborators are cited as important examples of their work. The square also has a history as a burial ground, execution ground and site of the 1864 Sanitary Fair.","narrative":"Logan Square is a public square in central Philadelphia, first planted in 1823 and later redesigned as a focal point of the Benjamin Franklin Parkway. The parkway, completed in 1918 to a plan by French planner Jacques Greber, cuts diagonally across the city grid from City Hall toward Fairmount. Today the square has a large central circle ringed by flower beds, with lawns and walkways to the west, north and east. Its institutions include the Franklin Institute, the Free Library and the Cathedral of SS. Peter and Paul. The centre of the circle holds the Swann Fountain, completed in 1924 by Alexander Stirling Calder with Wilson Eyre, with three bronze river figures above stepped basins. Nearby, a bronze Shakespeare Memorial of 1926 by the same collaborators shows Hamlet and Touchstone. The square is valued for its planned design and for these works, which show the collaboration between Calder and Eyre.","period_of_significance":"c. 1918-1926","architect_builder":"Jacques Greber (planner); Alexander Stirling Calder and Wilson Eyre (fountain and sculpture)","architectural_style":null,"criteria":[],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:34.306272-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/81000555.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/81000555/9f0443956a-800.webp","url_1600":"https://nationalhistoricalregister.com/media/81000555/9f0443956a-1600.webp","licence":"CC BY 2.5","author":"Jeffrey M.
