Cathedral of Our Lady of the Angels

Los Angeles, California

In the wake of extensive damage to the seat of the Archdiocese of Los Angeles from the California earthquake of 1994, a new facility was needed to service the 4 million Roman Catholics in the greater Los Angeles area. Collaborating with Design Architect Jose Rafael Moneo, LEO A DALY provided executive architectural/engineering services and management of the consultants for the 240,000-SF Roman Catholic Cathedral of Our Lady of the Angels. We also provided architectural and engineering support for liturgical art for the project. The centerpiece is a 128,000-SF, 3000-seat cathedral. The site includes a 23,000-SF residence for the Archbishop, resident clergy and visitors and a 55,000-SF conference center with parish offices and meeting rooms. Other amenities include a 2.5-acre plaza, cloister garden, 156-FT campanile tower, cafe and religious items store and 600-car underground parking garage.
