[2] The origin of the San Lorenzo Valley Museum began when Ralph Wilcox, Walt Bachrach, and John Holm met in March 1976 to establish the Boulder Creek Historical Society.

These included collecting and exhibiting artifacts, gathering historical information, and providing education through the museum and outreach programs.

[1] The Museum initially was housed on the second floor of an office building in southern Boulder Creek before relocating to its permanent home in the former Grace Episcopal Church.

The Grace Episcopal Gallery opened in December 1999 and was named the San Lorenzo Valley Museum, broadening its mission and scope.

That same year, the Museum signed an agreement between the Belardi Trust directors and Felton Library Friends[3] to use the building for a second branch.

The former Grace Episcopal Church building, located on State Route 9 in Boulder Creek, houses the San Lorenzo Valley Museum's main gallery, administrative office and information center.

It was completed in November 1906 and was listed to the National Register of Historic Places on December 19, 2006, the centenary of its construction.

The adjacent property to the south of the building was purchased for additional parking in 1966 and a Sunday school was built behind the church in 1977.

A local restaurateur, Nick Belardi, purchased the former church property with the intention of dismantling the building to rebuild a new home.

Following community activism of citizens interested in preserving the structure and the death of his wife, Belardi donated the land and the building to the town of Felton, with the stipulation that it would serve as a memorial.
