Matthias Baldwin Park is a two-acre (0.81 ha) public park at 423 North 19th Street in Philadelphia, Pennsylvania. In 1991, the park was dedicated as Franklin Town Park as part of the 50-acre development called Franklin Town. The Franklin Town Development Corporation was a private consortium which, along with City of Philadelphia officials, announced plans in 1971 to build a new "city-within-a-city" within ten years, in order to clear what they considered blight in a parcel just north of the commercial core of Philadelphia. The developers could earn a profit while the City tax base would increase. Eminent domain was threatened in order to remove the 600 inhabitants and business owners in the proposed development. The park was to be the apex of a new diagonal street called Franklin Town Boulevard and was to be the centerpiece of the development. By 1974 construction began but due to economic uncertainty in the 1970’s the project progressed in fits and starts, and still, 50 years later, is not completed. The park itself was a Percent for Art requirement of the developers of Franklin Town. Landscape artist Athena Tacha was commissioned to design the park, and the final version was the art piece titled Connections, which is made up of a terraced set of planting beds surrounded by a level surface with paved pathways and fifty trees. The park is one of the over 150 parks in the Philadelphia Parks and Recreation system. In 2009, many of the residents living in the neighborhood around the park had become disgusted by the many surface parking lots resulting from the demolition of their houses and businesses in the name of the desultory Franklin Town development. They petitioned the City to change the name of the park to Matthias Baldwin Park, which was officially done in 2011. For the same reason, the name of the neighborhood on the community bulletin board Nextdoor was changed from Franklin Town to Baldwin Park in 2019. Matthias W. Baldwin was a locomotive builder whose factories occupied most of the neighborhood from 1835 though 1928, at one time being the largest locomotive builder in the world. A State of Pennsylvania historical marker was placed at the northwest corner of the park in 2009 commemorating the location of the Baldwin Locomotive Works. The Friends of Matthias Baldwin Park, a non-profit volunteer group committed to maintaining and preserving the park, became involved in a national controversy in June of 2020. During protests after the murder of George Floyd, a statue of Matthias W. Baldwin at Philadelphia City Hall was defaced with the words "murderer" and "colonizer." Members of the Friends group were sought out for comments and educated a national audience on the fact that Baldwin was in fact an abolitionist, a defender of Black franchise, a donor for schools for Blacks, and a workforce integrator, all of which caused him to lose business in Southern states in the decades preceding the Civil War. Liberal and especially conservative news outlets caricatured the protestors as ignorant of history.

The Reading Company Grain Elevator was built as a grain elevator in 1925 by the Reading Railroad in Center City Philadelphia to replace an elevator that had operated on the same spot since the Civil War. The building was abandoned in the 1950s and refitted in the 1970, with the lower floor made into offices, the grain storage areas essentially untouched, and the upper levels made into penthouses.

The Philadelphia Pennsylvania Temple is a temple of the Church of Jesus Christ of Latter-day Saints (LDS Church) in the Logan Square neighborhood of Philadelphia. Completed in 2016, the intent to construct the temple was announced on October 4, 2008, during the church's 178th Semiannual General Conference by LDS Church president Thomas S. Monson. The temple is the church's first in the state of Pennsylvania, and the first temple between Washington, D.C. and New York City.

The Swann Memorial Fountain (also known as the Fountain of the Three Rivers) is an art deco fountain sculpture located in the center of Logan Circle in Philadelphia, Pennsylvania, United States.The fountain, by Alexander Stirling Calder designed with architect Wilson Eyre, memorializes Dr. Wilson Cary Swann, founder of the Philadelphia Fountain Society. The Society had been planning a memorial fountain in honor of its late president and founder. After agreeing that the fountain would become city property, the society was granted the site in the center of Logan Circle.Adapting the tradition of “river god” sculpture, Calder created large Native American figures to symbolize the area's major streams, the Delaware, the Schuylkill, and the Wissahickon. The young girl leaning on her side against an agitated, water-spouting swan represents the Wissahickon Creek; the mature woman holding the neck of a swan stands for the Schuylkill River; and the male figure, reaching above his head to grasp his bow as a large pike sprays water over him, symbolizes the Delaware River. Sculpted frogs and turtles spout water toward the 50-foot (15 m) geyser in the center, though typically the geyser only spouts 25 ft (8 m). The use of swans is a pun on Dr. Swann's name. Eyre designed the basin and the interlacing water jets, including the central geyser. During warm months, swimming in the fountain is a long-standing Philadelphia tradition. In the summer of 2006, the City of Philadelphia began enforcing a swimming ban with a nearly constant security presence, but the ban was eliminated in 2009. Besides serving as the center of Logan Square, the Fountain also stands as the midpoint on the Ben Franklin Parkway, which includes also sculptures by two other generations of the Calder family. Stirling Calder's father, Alexander Milne Calder, designed the statue of William Penn atop the tower of City Hall at the southeast end, while, at the Philadelphia Museum of Art on the northwest end, the mobile Ghosts is by Alexander Calder, Stirling Calder's son. This led to a local wit referring to the three sculptures as the Father, the Son and the Holy Ghost. For many years the fountain was framed by a magnificent circle of Paulownia trees, which have since been replaced. The fountain was mentioned in songs by the pop punk band The Wonder Years. The song "Logan Circle" from their album The Upsides opens with "They turned on the fountain today at Logan Circle"; there are several references to the fountain and the city of Philadelphia in the band's lyrics. It is the subject of the song "Spit Fountain" by Philadelphia emo band Algernon Cadwallader. It is also featured in the Philly level of Tony Hawk's Pro Skater 2 and in an episode of the television show It's Always Sunny in Philadelphia, "Dennis Reynolds: An Erotic Life".
