Grace Episcopal Church, Church and museum in Boulder Creek, California, United States

Grace Episcopal Church is an early 1900s church building in Boulder Creek that now functions as the main gallery for the San Lorenzo Valley Museum. The structure displays late Gothic Revival features including tall pointed windows and is constructed from local redwood timber.

The building was completed in 1906 and originally served the local faith community. After 1915 it went through several uses until the Boulder Creek Historical Society purchased it in 1995 and converted it into a museum.

The building was moved from the former town of Lorenzo to its present site on State Route 9. After the Episcopal congregation declined around 1915, the Christian Science Society bought it in 1923 and dedicated it as the First Church of Christ Scientist in 1978. The museum now keeps the original garden beside the church, expanded since 1995.

The main gallery sits on State Route 9 in Boulder Creek, with the archive and office in a climate-controlled annex built beside it in 2011. Admission is free, and funding comes partly from California Humanities and the National Endowment for the Humanities. The garden beside the church has been expanded and improved since the museum took over the property in 1995.

The building was moved from the former town of Lorenzo to its present site on State Route 9, and it was added to the National Register of Historic Places on December 19, 2006, exactly one hundred years after its completion. Its frame is old-growth redwood.
