Mighty Mick’s Gym was a gym managed and owned by Mickey Goldmill, manager and trainer of Rocky Balboa and a former boxer himself. After Mickey’s death in 1981, the gym closed and remained dormant for a long period of time. Several years later, after filing for bankruptcy because of a crooked lawyer, Rocky reopened the gym which Mickey willed to his son Robert Jr. Besides Rocky, other boxers who trained at Mighty Mick’s were “Big Dipper” and Tommy Gunn. 
A “flatiron”-style three story building in the Kensington neighborhood of Philadelphia, PA. The building was seen worldwide in the 1976 film Rocky, and its sequels, as the site for the fictional characters Mickey Goldmill’s gym, where the eponymous protagonist first trained. The interior shots were filmed in Main Street Gym in Los Angeles, as the building is not in fact a gym.
