Christian Science Reading Room at 1133 8th Street in Coronado provides a quiet study space and lending library stocked with Bible editions, Science and Health with Key to the Scriptures by Mary Baker Eddy, and the Christian Science Monitor newspaper. The room is operated by First Church of Christ, Scientist next door at 1123 8th Street, an Irving Gill-designed 1928 structure that earned Coronado Historical Association landmark designation on June 15, 1980. Visitors may read, borrow, or purchase study materials regardless of faith background, with the reading room functioning as both a lending library and a bookshop within the 92118 ZIP on Coronado Island. Gill's design for the church incorporates cast-concrete walls, a symmetrical facade with recessed archways, tall arched windows, and a central skylight that illuminate the main congregation room without artificial light — elements drawn from the same California-mission vocabulary visible in his La Jolla and Coronado commissions. Lofted above the main hall is an organ pavilion housing a pipe organ built directly into the walls in 1928, with pipes running through the concrete structure itself. The church, formally chartered in 1916, has received multiple Coronado Flower Show landscape awards for its grounds on the corner of 8th Street and C Avenue, three blocks off Orange Avenue and the Coronado shopping corridor that runs toward Hotel Del Coronado. Gill's architectural legacy on Coronado Island is cataloged by the Coronado Historical Association and Coronado Museum on nearby Loma Avenue, adding architectural tourism to the list of things to do in Coronado beyond Coronado Beach and the Coronado Ferry Landing. The reading room's flat-roofed annex mirrors Gill's stripped-classical geometry, with breezeways and ground-level arches providing natural ventilation characteristic of his early-twentieth-century Southern California work.
