St Paul's Episcopal Cathedral at 2728 Sixth Ave serves as the seat of the Episcopal Diocese of San Diego, tracing its origins to the first Protestant congregation organized in San Diego in 1853. The cathedral's child education ministry operates through St. Paul's Child Care Program, extending the parish's service to families across the 92103 ZIP code. Architect Philip Frohman, who also designed the National Cathedral in Washington, D.C., created the neo-Gothic sanctuary completed in 1951, incorporating Romanesque elements and an organ whose oldest pipes date to 1887. Community receptions and off-site events draw on neighborhood venues such as Skylight Venue in the Hillcrest events district. The cathedral maintains a three-choir music program, hosts a full calendar of public concerts and chamber recitals, and operates the Pacific Academy of Ecclesiastical Music.
