Infinite Loop

The Apple Campus was the corporate headquarters of Apple Inc. from 1993 until 2017, when it was largely replaced by Apple Park, though it is still used by Apple as office and lab space. The campus is located at 1 Infinite Loop in Cupertino, California, United States. Its design resembles that of a university, with the buildings arranged around green spaces, similar to a suburban business park.

Apple's corporate headquarters was originally located at Building 1 on 20525 Mariani Ave in Cupertino. The land east of Mariani One across De Anza Boulevard where the campus was built was originally occupied by the company Four-Phase Systems . It has an area of 850,000 square feet . Construction began in 1992 and was completed in 1993 by the Sobrato Development Company. Before 1997, activities held on the campus were exclusively research and development. Until that time the buildings were referred to as R&D 1-6. With the return of Steve Jobs to Apple in 1997, changes were made to the campus: Apple increased the number of occupied buildings, and many activities not related to R&D were moved to the buildings on Infinite Loop, at which point they began to be referenced by their IL # designations. Steve Jobs left additional marks on the campus, for example, banning employees' pets and dramatically improving the cafeteria menu.
