On October 3, 1920, the Dayton Triangles played the first game of the National Football League, defeating the Columbus Panhandles 14-0 at Triangle Park in north Dayton.
In 1916, the Dayton Triangles, an amateur football team, was organized. The team consisted of employees from three Dayton factories: DELCO, Dayton Metal Products, and the Domestic Engineering Company. Their factories formed an industrial triangle in downtown Dayton giving the Triangles their name. This building was one of two locker rooms located on their home field at Triangle Park.
The Dayton Triangles was a charter member of the American Professional Football Association, organized in Canton, Ohio on September 17, 1920. The name of the association was changed to the National Football League in 1922.
Built circa 1916 in Triangle Park in Dayton.
