What drives Gilroy’s History grade

On its age, its old homes and the National Register, Gilroy is more historic than 46% of U.S. towns, #176 of 847 in California. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.

B−

All U.S. towns we grade (21,289)Ahead of 46%

California towns of 2,500+ (847)Ahead of 79%

Few California towns list much on the Register (a typical California town has 0.0 per 10,000 residents, the U.S. 2.4), so Gilroy’s 1.5 sits above most of its state (79% of California towns have fewer) while its 9 listings outnumber those of 75% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would range from C− to B. The pre-1940 share (±1.0 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata’s 1870 falls in the same era, so the grade doesn’t depend on which one is used.

Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

Spanish explorers led by Juan Bautista de Anza first passed through the Santa Clara Valley area in 1776. More than 20 years later, Spanish missionaries established Mission San Juan Bautista in 1797 near the Pajaro River. In 1809, Ygnacio Ortega was granted the 13,066-acre (5,288 ha) Spanish land concession Rancho San Ysidro.

the present town of Visalia. Thence, by every point of the compass, hunting for game, and at length reached Sobrianos, on the Salinas, near the Mission of Soledad.

Here he remained until 1850, when he moved to his present residence, about a mile from the new town of Gilroy, wdiere he has since resided. Some twenty years ago he was deprived of his sight.

fogs drop their refreshing moisture pleasantly, having lost their rawness in their mountain climbing. The swelterinij heat often encountered at the depot by railroad travelers, who halt for their midday meal, has unjustly given the City of Gilroy a torrid name, but such is only the dictum, of the bird of passage, observation, both barometrical and thermometrical, proving the undoubted salubrity of the township.
