input: The auditorium opened as the Union Gospel Tabernacle in 1892. Its construction was spearheaded by Thomas Ryman (1843–1904), a Nashville businessman who owned several saloons and a fleet of riverboats. Ryman conceived the idea of the auditorium as a tabernacle for the influential revivalist Samuel Porter Jones. He had attended one of Jones' 1885 tent revivals with the intent to heckle, but was instead converted into a devout Christian who pledged to build the tabernacle so the people of Nashville could attend large-scale revivals indoors. It took seven years to complete and cost US$100,000 (equivalent to $3,015,926 in 2021). Jones held his first revival at the site on May 25, 1890, when only the building's foundation and six-foot (1.8 m) walls had been completed.
