The Cathedral of the Holy Cross, by Elkus Manfredi Architects

This project was selected as an honorary winner in the 2022 ARCHITECT Architecture & Interiors Awards, Architecture: Historic Preservation category.

“The finest designers and builders of their time originally created the Cathedral of the Holy Cross. The love, respect and skill it takes to preserve such a structure shows the nobility of the design profession. — Juror Joey Shimoda, FAIA

Boston’s Holy Cross Cathedral is the largest Catholic church in New England. The complete renovation and remodeling of the neo-Gothic monument designed by Patrick Keely in 1875 in the south of the city by local architects Elkus Manfredi reimagines the previously dark and ominous interior of the structure as a beacon of light for the large Catholic community of Boston as the church nears its sesquicentennial.

Since the original drawings of the church have been lost, the architects used detailed laser scans to create a new 3D digital model of the building. New interior finishes have maintained the qualities of light and permanence, including new white and light gray marble floors throughout. The nave was reconfigured for greater accessibility while maintaining the overall seating capacity of 1,900, and the sanctuary was redesigned to remove elements from an overcrowded 1980s renovation. The architects designed a new family of appointments you liturgical and furnishings, including joinery and works of art, for the church.

The wooden trusses carrying the ceiling have been cleaned and sealed, with a front edge treatment of maroon paint replaced with shiny metallic gold that emphasizes the original details of the church. New M/E/P systems, including energy-efficient lighting, air conditioning, AV, broadcast and television, have been seamlessly integrated into the building.
