Harmony Grove Church
Also known as: Harmony Grove Methodist Episcopal Church
Why it's listed
Harmony Grove Church is a one-story brick church on East Locke Road near Lockeford, San Joaquin County. Its cornerstone was laid in 1859 and the building was finished in 1861, with brick made locally by Chinese workers at a brickyard on Dr. D.J. Locke's ranch. John Brakeman supervised construction and James Tallmadge laid the brick. In 1868 the congregation, enlarged after a revival, had the roof raised and the windows and door changed to pointed Gothic forms, leaving features of both Greek and Gothic Revival on the building. Believed to be the oldest surviving Protestant church in California's Central Valley, it grew from a union Sunday School begun in 1854. Most of its congregation moved to a new Lockeford church in 1883, and funerals were held there as late as 1918. After a 1965 sale threatened demolition, residents campaigned to save it, and a restoration was completed in 1973. It is listed for its role in early settlement and religion and for its architecture.
Significance in brief: The nomination argues significance under Criterion A at the local level for Early Settlement and Religion, as believed to be the oldest surviving Protestant church in California's Central Valley. Under Criterion C it is a rare example of the fusion of Greek and Gothic Revival styles, a vernacular interpretation reflecting local building practices.

What listing means for this property
Religious properties are listed for their architectural or historical significance, not their religious use. Listing is honorary and does not restrict the congregation's use of the building. The federal rehabilitation credit is generally unavailable unless part of the building is income-producing; some state programmes and preservation grants do cover religious buildings. Federal funding or permits trigger Section 106 review.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
