Standing in the midst of downtown Los Angeles, the Cathedral of Our Lady of the Angels serves the total Archdiocese of over 5 million Catholics. As the heart of all 287 Parish Churches and communities, it is the place where the Archbishop celebrates the major Liturgies of the year with clergy, religious and laity.

The Cathedral serves as a "model Church for all Parish Churches" in the style and content of its liturgical celebrations. In design, art and furnishings, the Cathedral is rich in cultural diversity in a city in which Sunday Mass is celebrated in 42 different languages.
