Holy Trinity Church
Why it's listed
Overlooking Trinidad Harbor on a south-sloping lot at Parker and Hector Streets, this small wood-frame church was built in January 1873 by Purcell and Griffith. Its first pastor, Father Michael Walrath, organized the project, with land and lumber donated locally and about $1,400 raised from townspeople. The church seats roughly 60 in the nave, with a choir loft, a small bell tower and white lap siding. The name recalls the Spanish landing on Holy Trinity Sunday, 1775. After decades of disrepair it was restored in 1955 and rededicated, though the siding was replaced and the steeple is smaller than the original. It is the oldest standing building in Trinidad. Beyond worship, it hosted town council meetings and community gatherings in the late 1800s, when the north coast was reached mainly by sea. Its simple carpenter-built design, with lancet windows hinting at Gothic Revival, reflects that isolated setting.
Significance in brief: It is the oldest building still standing in Trinidad and is tied to the growth of the Catholic community on California's isolated north coast in the late 19th century. It is a simple carpenter-built vernacular interpretation of Gothic Revival church design, using redwood. The church also served as a community meeting place for the town council and for social events.

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.
