It included a gymnasium and other facilities for members, as well as a large arena lit by electric lighting - still something of a novelty at the time.
Sports writer S. Derby Gisclair called it "the epicenter of professional boxing" in the era.
The most famous of boxing matches held at the Olympic Club were a series of World Championship matches held on consecutive days in September of 1892, including Featherweight and Lightweight championship matches cumulating in James J. Corbett defeating John L. Sullivan for the World Heavyweight Championship.
On April 6, 1893, the longest fight in professional boxing history took place at the Olympic Club, as Andy Bowen fought Jack Burke for the Lightweight Championship.
The match lasted 110 rounds, over seven hours and 19 minutes (each round lasting three minutes) before referee John Duffy declared a "no contest", both men having become too dazed and tired to come out of their corners.
