Facebook (Meta) Headquarters - 1 Hacker WayStop on Silicon Valley Tech Heritage Tour, a free self-guided tour.Meta's headquarters in Menlo Park at 1 Hacker Way houses one of the world's most influential social media companies. Founded by Mark Zuckerberg in his Harvard dorm room in 2004, Facebook moved to Silicon Valley that summer, initially operating from a house in Palo Alto. The company has since grown to billions of users worldwide. The headquarters campus features the famous blue Facebook Like button thumb sculpture, which has become one of Silicon Valley's most photographed landmarks. The main building, designed by Frank Gehry, features a 9-acre rooftop park with walking trails, over 400 trees, and outdoor workspace - an innovative approach to corporate architecture. The campus includes the Facebook sign where visitors take photos, though most buildings are restricted to employees and guests. The address, 1 Hacker Way, reflects tech culture's positive embrace of hacker ethic - solving problems through clever technical solutions. Meta's evolution from college social network to global communication platform, including acquisitions of Instagram and WhatsApp and recent pivot to virtual reality and the metaverse, illustrates how Silicon Valley companies continuously reinvent themselves. The campus represents the social media era's impact on Silicon Valley, where connecting people became as important as building hardware or software.Stops on this tourHP Garage - The Birthplace of Silicon ValleyStanford University CampusShockley Semiconductor Laboratory SiteComputer History MuseumGoogleplex - Google HeadquartersGoogle's First Office - The Menlo Park GarageFacebook (Meta) Headquarters - 1 Hacker WayApple's Original Garage - 2066 Crist DriveApple Park - The Spaceship CampusIntel Museum and HeadquartersThe Tech InteractiveNASA Ames Research CenterSand Hill Road - Venture Capital RowXerox PARC (Palo Alto Research Center)Buck's of Woodside RestaurantTesla Headquarters and ShowroomsFairchild Semiconductor SiteOracle Campus and Oracle Arena HistoryLinkedIn Headquarters - Mountain ViewNikola Tesla Statue and Silicon Valley Time Capsule
