Old St. Mary's Cathedral

  • Northern California

Old St. Mary’s Cathedral is the first purpose-built cathedral building in California. The building was erected in 1854 for the San Francisco Archdiocese, which ministered to the entire Pacific coast at that time. One of the oldest brick buildings in San Francisco, the exterior survived the 1906 earthquake though interior elements were lost to fire. It is a California Historical Landmark and City of San Francisco Landmark No 2.

ARG's multiphase project at Old St. Mary's included preparation of a master plan for rehabilitation, exterior restoration guidelines, seismic strengthening of the unreinforced masonry structure, ADA and life-safety upgrades, exterior architectural rehabilitation, and interior liturgical improvements. ARG's three disciplines, architecture, conservation, and history and planning, collaborated on the rehabilitation.
