Pleasanton has one of the best-preserved historic main streets in the Bay Area and one of the least accurate names in California. Both of those facts are worth a few minutes.
Start with the name
The town is named for Alfred Pleasonton, a Union cavalry general in the Civil War. Note the spelling. Somewhere between the proposal and the paperwork in Washington, a clerk dropped the "o" and wrote Pleasanton, and nobody ever fixed it.
So the city is named after a man whose name it does not spell correctly. It has been that way since 1894.
Before it was pleasant
The land was Rancho Santa Rita, a Mexican grant. But before the city incorporated on June 18, 1894, the settlement here was called Alisal, and its reputation was the opposite of the one the town has now.
Alisal was a Gold Rush-era hangout for bandits and men avoiding attention — local histories have long called it the most desperate town in the West. That's a nickname repeated down the generations rather than an official designation, so take it in the spirit it's offered. But the through-line is real: this valley was rough country before it was comfortable country.
Main Street
Downtown Pleasanton is a genuine nineteenth-century main street that survived. Gothic Revival, Italianate and Queen Anne storefronts from the mid-1800s, still standing, still in commercial use. A 1990s streetscape redesign widened the sidewalks, which is why the outdoor dining works as well as it does.
The Museum on Main, at 603 Main Street, handles the local history and runs an active program. It's small and it's good, which is the correct combination for a town museum.
The Fairgrounds
The Alameda County Fairgrounds are the thing Pleasanton is known for beyond the Tri-Valley, and the numbers are bigger than people assume: around half a million guests over the summer fair, and more than three hundred event days a year. It runs as an independent nonprofit rather than a county department.
The racetrack is the real artifact. It was built in 1858 by the Bernal family — a one-mile dirt oval, and it's billed as the oldest of its kind still operating in the United States. That predates the transcontinental railroad. It predates the county fair it now sits inside. Horses have been running on that ground for more than a century and a half.
The Hearst estate that became a country club
This is the piece of Pleasanton history that surprises people.
Phoebe Apperson Hearst — philanthropist, University of California regent, mother of William Randolph Hearst — built a fifty-room estate here in 1903 called Hacienda del Pozo de Verona. It was a serious house, on serious grounds, built by one of the most consequential women in California at the time.
That property became Castlewood Country Club, which is still operating today. Most of the people who play there know it's old. Fewer know whose house it was.
Where it stands now
Pleasanton is one of the most expensive places in the East Bay — the median home sale price sat above $1.6 million in mid-2026, and the median household income is roughly $186,000. Unusually for the region, prices have been flat to slightly down rather than climbing.
The economy isn't just bedroom-community commuting anymore either. Hacienda Business Park and the corporate presence around it — Workday is headquartered here with thousands of employees — mean a lot of people who live in Pleasanton also work in Pleasanton. That's rare on this side of the hills and it changes the feel of the place.
What hasn't changed is Main Street. It is still the center of town, still walkable, still full on a Saturday. A lot of California towns lost that. This one didn't.
