Apple Park, the much-talked-about project in Cupertino, Calif., formerly referred to as Apple Campus 2, is opening to employees in April, the company announced this week. London firm Foster + Partners designed the project, which features a 2.8 million-square donut-shaped building "clad entirely in the world’s largest panels of curved glass," according to an Apple press release. The building also includes the newly named Steve Jobs Theater, opening later in the year.

Spanning 175 acres, the campus will also include parklands, an employee fitness center, R+D facilities, and a visitors center complete with an Apple store and public café.
