The old parish church traces its origin to the year 1902, when a group of
Jesuit priests arrived in Shreveport to establish and staff a new parish and high school for boys. The parish's first
rector was Fr. John F. O'Connor, S.J. By 1924, building a larger church was deemed necessary for the growing congregation. The
cornerstone of the structure was laid on 31 July 1927. The church was designated a
co-cathedral for the Diocese of Alexandria–Shreveport in 1977. That diocese was split, however, on 23 June 1986, creating the Diocese of Shreveport. St. John Berchmans became the cathedral church of the new diocese. The school is now co-educational for grades Pre-K-8. One of its notable alumni is
Don Hathaway, the
sheriff of
Caddo Parish from 1980 to 2000. The cathedral was renovated in 2014; the High Altar and Tabernacle were restored and some elements installed in the 1992-1994 renovations were removed. ==Architectural details==
