Graham Memorial Presbyterian Church in Coronado was built in 1890 from a design by James W. Reid — the architect of Hotel Del Coronado — as a memorial funded by Isabella Graham Babcock, wife of the Hotel Del's builder Elisha Spurr Babcock Jr., on Coronado Island's C Avenue in the 92118 village. The campus shares C Avenue's education corridor with the island's faith-based schools, including Sacred Heart Parish School a few blocks south, anchoring a Presbyterian presence that predates Coronado's incorporation as a city. The Reid-designed sanctuary connects the church to the same architectural lineage as Hotel Del Coronado on Orange Avenue — a provenance that gives the building historical significance in a community where Victorian and early-California structures define the island's character. Worship follows Presbyterian Church (USA) liturgy with traditional hymns, scripture readings, and a sermon-based order of service, and the congregation supports community outreach that includes food drives, holiday gift programs, and partnerships with island nonprofits serving military families at Naval Air Station North Island. The ecumenical fabric of Coronado Island's worship community means Presbyterian congregants share civic events, charitable drives, and interfaith services with Methodist, Episcopal, Catholic, and Lutheran neighbors, including the congregation at St. Paul's United Methodist Church on D Avenue. C Avenue runs parallel to Orange Avenue two blocks east, connected by the flat village grid that makes Coronado Beach, the Coronado Ferry Landing, and every commercial destination on the island accessible on foot or by bicycle from the church campus. The Babcock family's role in founding both Hotel Del Coronado and this memorial church ties the congregation's origin story to the Coronado Bridge-era resort development that shaped the island's identity.
