Google headquarters is called "The Googleplex", which comes from the word "googolplex", meaning a 1 followed by hundredth power of the ten zeros.
The Googleplex is the corporate headquarters complex of Google and its parent company Alphabet Inc. It is located at 1600 Amphitheatre Parkway in Mountain View, California, United States.
The original complex, with 2,000,000 square feet (190,000 m2) of office space, is the company's second-largest square footage assemblage of Google buildings, after Google's 111 Eighth Avenue building in New York City, which the company bought in 2010.
"Googleplex" is a portmanteau of Google and complex (meaning a complex of buildings) and a reference to googolplex, the name given to the large number 10(hundredth power of the ten).
