The church web site says:
1844: The cornerstone of the present St. Mary of the Seven Sorrows was laid. Delays and lack of funds postponed the dedication and completion of this first Cathedral of the Diocese of Nashville. Being so close to the old Church on Capitol Hill, this latter structure was soon abandoned and was turned into a hospital run by the Sisters of Charity. Fire destroyed a great part of the structure, and it was abandoned in 1856. Salvaged materials from this structure were used in the building of the Church of the Assumption in North Nashville.
