Purissima

California wrote the book on ghost towns, from Gold Rush tent cities to Owens Valley farm towns the aqueduct dried up.

Purissima is a ghost town in southwestern San Mateo County, California, United States, near the junction of State Route 1 and Verde Road. Purísima means "purest" in Spanish and is most commonly used in Spanish to refer to La Purísima Concepción (the Immaculate Conception) of the Virgin Mary (note historical misspelling in English resulting in double "s", or the result of the Holstein pronunciation with use of the "ẝ" being mistaken as ß "ss", or perhaps spelling comes from the local Portuguese influence, where the spelling from A Puríssima Conceição would be correct).

The on-the-ground condition of Purissima is unverified — it's listed here with unknown status. That could mean standing buildings, or an empty field. Go prepared for either, and consider sharing what you find so the record improves.

Nobody has confirmed the access situation, so treat any visit as reconnaissance: verify land ownership first, and be ready to admire from the road.

Here's the honest truth: access to Purissima is unverified. We couldn't confirm whether the site sits on public land, private property, or something in between — so verify land ownership and local rules before visiting, and respect private property at all times.

Ghost-town etiquette is simple: take only photographs. Removing artifacts is illegal on public lands and disrespectful everywhere else — and on federal land it can be a serious offense.
