Philly’s 17 Most Endangered Properties

The Philadelphia Preservation Alliance has released its annual list of endangered properties, which you can peruse using a map from Curbed Philly. Among those in danger of demolition, disrepair or undue neglect are Joe Frazier’s gym, John Coltrane’s house, the S.S. United States, and the entirety of Logan Square. The Forum, inexplicably, did not make the list. [Curbed Philly]
