I know it’s hidden off the street & looks like a fire station or just a house but it is a museum I promise! I went to Ohlone a hundred times before noticing the little sign(& I’m very observant!) so I’m not surprised I’m the 1st person to review this. Anyway I definitely suggest going! It’s small, but it packs alot in there! They have stuff ranging from fossils to Indian artifacts, and household items from the 1880s to the 1980s. Lots of interesting facts not just about Fremont– but also about nearby cities. Like did you know Teddy Ruxpin was invented in the 510? Cool stuff like that is crammed in here! The fee is cheap [I think it was a $ 2 donation]. There was a gift shop area [mostly books]. I remember the hours were wonky [cuz it’s volunteers only]. But go by & see if it’s open. If you have enough time to go to the Mission SJ down the street– this is also worth a visit :)
