Portuguese whalers came ashore in the South Bay, became dairy farmers, and built a hall in 1940 that still feeds strangers every July
Newark is the five-square-mile city on the east shore of the Dumbarton Bridge that most of the Bay Area only knows as the exit before the bridge. It has a piece of immigration history I think is genuinely underrated.
The first Portuguese arrivals in that part of the East Bay didn't come as farmers. They came as whalers and seamen working the Pacific trade routes, and once they came ashore a lot of them never went back out. They moved into dairying and farming on the marshy flats that later split into Newark and Fremont. By the early 1900s they were gathering informally on St. John's Day, and on September 18, 1921 that loose tradition organized formally as Council Number 8 of the Sociedade Espirito Santa.
Nineteen years later, in 1940, the community bought the grounds outright and put up a building. That's the part that gets me. Immigrant families, many one generation off a ship, in a farm town of a few thousand people, went from an informal annual gathering to owning the land and the hall in under two decades. And it never lapsed. The Holy Ghost Festa still runs every fourth Sunday of July, roughly twelve thousand pounds of beef get blessed, and a parade goes to St. Edward's. It's open. Strangers eat. That's the entire design of the thing.
There's a version of Bay Area history where everything interesting happened in San Francisco or Oakland, and then a hundred-year continuous tradition turns up behind a supermarket parking lot in Newark. Fuller writeup here: https://adam-modzeleski.weichertrainbow.com/blog/68/
