First Church of Christ, Scientist in Coronado occupies a 1928 Irving Gill-designed building at the corner of Eighth Street and C Avenue in the 92118 village, three blocks east of Orange Avenue on Coronado Island. The adjacent Christian Science Reading Room at 1133 Eighth Street provides a public library of writings by Mary Baker Eddy and publishes the Christian Science Monitor, extending the church's educational mission beyond Sunday services into daily access to spiritual healing literature. Irving Gill's architectural contribution to Coronado includes both this church and Sacred Heart Church on C Avenue — two structures that represent his stripped-classical, proto-modernist California style and that hold historic significance alongside Hotel Del Coronado, the Spreckels buildings, and the Victorian homes that define the island's built landscape. Sunday and Wednesday services follow the Christian Science denomination's format of Bible readings paired with correlative passages from Eddy's Science and Health with Key to the Scriptures, and the congregation maintains a Sunday school for children and young adults. The Eighth Street location sits within the walkable village grid that connects every block on Coronado Island to the Orange Avenue commercial corridor, Coronado Beach, the Coronado Ferry Landing, and the Coronado Bridge approach. Military families stationed at Naval Air Station North Island and longtime 92118 residents share the congregation, and the church's proximity to children's programs at institutions such as My Montessori School Coronado embeds it in the island's family-service network. The Reading Room's walk-in format welcomes visitors exploring the Coronado shopping corridor on Orange Avenue to study Christian Science texts in a quiet, non-worship setting.
