|Built c.1895 as a window sash and blind warehouse, Joe Frazier's Gym is significant under Criterion B for its association with the career and life of Joe Frazier, the Olympic and Heavyweight Champion boxer who defeated Muhammad Ali in the Fight of the Century in 1971. The resource is significant in the Area of Entertainment/Recreation for its association with Frazier and its use as a training facility for several of the twentieth century's highest-profile boxing matches. Located in a mixed residential and industrial neighborhood in north Philadelphia, PA, the gym (originally named Cloverlay Gym, by Frazier's group of investors) served as Frazier's training center for his highest-profile fights, including his world championship bouts with Ali, George Foreman, and others. After Frazier's retirement from boxing in 1975, he bought the gym from the investment group and changed its name, reopening it to the public as Joe Frazier's Gym. Over the next 25 years, Frazier invested most of his time and prize money in the gym, where he trained the next generation of boxers (including National Golden Gloves Heavyweight Champion Duane Bobick and Olympic medalist Terrance Cauthen) and offered local inner-city youth opportunities away from the distractions and dangers of the streets. As Frazier's wealth and health declined late in his life, the gym also became his home, as he lived in the apartment above the training space. Plagued by debt and back taxes, he closed the gym in 2008, just a few years before his death from liver cancer in November, 2011. Joe Frazier's Gym is an important building associated with Frazier's life and productive career, and serves as a powerful representation of both African-American and boxing history in twentieth-century Philadelphia. Joe Frazier's Gym meets Criterion Consideration G, as though his accomplishments and active career may have taken place within the last fifty years, it is clear that Frazier is an important figure in late 20th century boxing history, this building best reflects his success and lasting impact within the sport, and this building is very important within the city of Philadelphia's African American sports resources. The period of significance represents the duration of Joe Frazier's involvement with the building, from 1968 to 2008.
