Hidden History Project
Your guide to Valley history
Free · Designed for iPad. Not verified for macOS.
Effortlessly discover the stories lying just around the corner with Hidden History.
By notifying users when they near sites of historical significance primarily around the greater Palo Alto area, Hidden History hopes to forge new connections between the land and the locals.
Although history isn’t always easy to see in Silicon Valley, it’s everywhere. Whether you’re on your morning jog or evening commute, the Hidden History Project hopes to make it easier for you to find it.
History is scientifically proven to facilitate a sense of place. Whether you were born and raised in Silicon Valley or moved in a year ago, history can motivate you to engage with and invest in your communities.
