Apple Campus, Corporate headquarters building complex in Cupertino, United States
Apple Campus is an office complex at 1 Infinite Loop in Cupertino, California, made up of six four-storey buildings numbered IL1 to IL6 along a private U-shaped street, set among landscaped green spaces in a layout resembling a university campus. The complex covers 850,000 square feet (79,000 m2) on a 32-acre (130,000 m2) site at the southeast corner of Interstate 280 and De Anza Boulevard.
The land east of Mariani One was held by Four-Phase Systems, later acquired by Motorola; Apple bought it for a discounted $25 million after the 1989 earthquake damaged it. Sobrato Development Company built the campus in 1992–1993, and the six buildings were called R&D 1–6 until Steve Jobs returned in 1997 and they became IL1–IL6.
The private U-shaped street is named Infinite Loop after the programming concept, and together with Mariani Avenue it forms a circuit that can be driven round indefinitely. Employees call the six buildings IL1 to IL6, and IL4 holds the 300-seat Town Hall auditorium and Caffè Macs.
The six buildings sit on a private U-shaped street, Infinite Loop, which joins Mariani Avenue to form a circuit; the main address is 1 Infinite Loop. The campus store, once the only place selling Apple merchandise, closed on January 20, 2024, so the site is now offices and laboratories rather than a public stop.
The private street is named for the programming concept of an infinite loop: together with Mariani Avenue it forms a circuit that can be driven round indefinitely. Each of the six four-storey buildings carries a single digit, so employees say IL1 to IL6 for Infinite Loop 1–6.
