The pipe organ is a notable instrument used regularly for both liturgical accompaniment and public concerts.
The cathedral serves as the site for major diocesan celebrations, including the Chrism Mass held annually during Holy Week.
St. Mary's Cathedral of the Immaculate Conception serves as the seat of the Archbishop of the Roman Catholic Archdiocese of Portland in Oregon. Originally dedicated in 1926, the current structure is built in a Romanesque Revival style with prominent Italian influence. The cathedral is noted for its high-arched ceilings, ornate stained glass windows, and a significant pipe organ installation. It serves as a central hub for the local Catholic community and liturgical events. The building is constructed of brick and terra cotta, reflecting the architectural trends of its founding era in Portland's Northwest District.
