About the Parish

The Historic First Catholic Church of Jacksonville

The Basilica of the Immaculate Conception was founded in 1854, and was the first church named after Pope Pius IX declared the Dogma of the Immaculate Conception on December 8, 1854.
On this date the Immaculate Conception Church, graduating from the role of a mission church, was formally established as a parish.

The Basilica of the Immaculate Conception has a
rich history as one of the oldest Catholic Church’s in north Florida. It is without doubt a magnificent testimony to the faith of the Catholic community of the late 18th and early 19th centuries, who desired a place to worship and from which to share the Gospel. To accomplish their goals, they spared no expense and willingly sacrificed for the salvation of all.

The Basilica of the Immaculate Conception continues to be a spiritual home, a light of Christ in the City,
and a refuge to sinners seeking the mercy of God’s love outpoured.
