Apple Campus 2, Corporate Headquarters Of Apple Inc., Cupertino, California, United States

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 formerly occupied by the company Four Phase Systems (later acquired by Motorola). It has an area of 850,000 square feet (79,000 m2). Construction began in 1992 and was compeleted 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 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.
On the night of August 12, 2008, a fire broke out on the second floor of the building Valley Green 6. The firefighters worked for hours until the following morning to extinguish the fire. No injuries were reported, but the forty-year-old building suffered USD $2 million of fire damage.
