[1] St. Ignatius Loyola was established as a parish of the Archdiocese of Miami on June 25, 1970, by Archbishop Coleman Carroll.

The first Mass for the parish was celebrated at Palm Beach Gardens Community High School for less than two dozen people on July 5, 1970.

While it was being built Pope John Paul II established the Diocese of Palm Beach on June 16, 1984.

The wood reredos and the marble sanctuary furniture was a part of an early 21st-century renovation.

The Diocese of Palm Beach website describes this cathedral was designed to use natural light and the exterior walls are of native Florida coral.
