Facebook Headquarters
Whether you ‘like’ it or not, Facebook has pretty much taken over the world and all of our social lives just within the past few years, and it all started in the small city of Menlo Park. An iconic Silicon Valley site and hometown success, the original Facebook Headquarters is a must-see if you’re visiting the Peninsula. Snap a pic next to the big thumbs-up and be THAT person on your high school friends’ news feeds.
