Church of the Immaculate Conception

Boston, MA 

Immaculate Conception Church was dedicated in 1861, and houses the largest surviving organ built by Elias and George Greenleaf Hook, inaugurated in 1864.


The acoustical concerns for renovation were to maintain the wonderful environment for organ performance, to provide a highly-flexible sound system for a variety of activities within the Sanctuary, and introduce a group of small meeting rooms in the side aisles of the main floor requiring concentrated privacy and relative quiet. Legal proceedings by the Boston Landmarks Commission to stop renovation were resolved by demonstrating superb acoustics to everyone’s satisfaction. Immaculate Conception Church continues to host a regular schedule of organ recitals, other concerts, and liturgical celebrations.
