The Tech Museum of Innovation, or simply The Tech, is a museum located in the heart of Silicon Valley, in downtown San Jose, California USA. Planning began in 1978 by members of the Junior League of Palo Alto and later assistance by the San Jose Junior League. The first 20,000-square-foot (1,900 m2) temporary exhibit finally opened in 1990 “The Garage” as it was named, opened in San Jose’s former convention center. On October 31, 1998, it opened a brand-new 132,000-square-foot (12,300 m2) facility, and has had 4,000,000 visitors.
The museum is composed of three floors, each with its own significance. The ground floor has the main entrance, a gift shop and cafe, the Imax theater, and a recreational area that is reserved for special events. The Tech Store contains various gifts, shirts and souvenirs. Café Primavera offers a varied menu of pasta dishes, sandwiches, pizzas, soups and salads for both adults and children. The ground level is a location where Segway and other robotic demos are displayed and given. The Tech Museum's architecture is the work of Mexican architect Ricardo Legorreta.
Four major theme galleries fill the upper level and lower level of the museum: Communication, Exploration, Innovation and Life Tech. These galleries are constantly being revamped and changed to fit the theme movies and exhibits. On the lower level there is also a public piece of artwork titled “Origin”, which is inside a 45-foot-tall (14 m) cylinder.
