The Cathedral Basilica of the Immaculate Conception serves as the mother church for the growing faith community of almost 500,000 Catholics, in 144 parishes and missions spread throughout northern Colorado.

The Cathedral houses the kathedra, or chair, from where the Archbishop carries out his service to the Church of Denver as Teacher and Shepherd. Locally, the Cathedral Parish is a spiritual haven for over 700 households.

Our website is an exercise of the Church’s commitment to “Go out and teach all nations”… the Good News of Jesus Christ. We hope and pray God’s blessings for you and yours! Come visit us sometime… and again, welcome!
