cam·pus

The word "campus" derives from a Latin word for "field" and was first used to describe the large field adjacent Nassau Hall of the College of New Jersey (now Princeton University) in 1774. The field separated Princeton from the small nearby town.

Some other American colleges later adopted the word to describe individual fields at their own institutions, but "campus" did not yet describe the whole university property. A school might have one space called a campus, another called a field, and still another called a yard.

The word campus has also been applied to European universities, although most such institutions are characterized by ownership of individual buildings in urban settings rather than park-like lawns in which buildings are placed.

Traditionally a campus is the land on which a college or university and related institutional buildings are situated. Usually a college campus includes libraries, lecture halls, residence halls, student centers or dining halls, and park-like settings.

Sometimes the lands on which company office buildings sit, along with the buildings, are called campuses. The Microsoft Campus in Redmond, Washington, is a good example of this usage. Hospitals and even airports sometimes use the term to describe the territory of their respective facilities.

So, a modern campus is a collection of buildings and grounds that belong to a given institution, either academic or non-academic. More examples include the Googleplex and the Apple Campus.

Apple is already known for its lavish and innovative campus environments, such as the massive ring-shaped building at the company's campus at Apple Park in Cupertino, California. The company has had a corporate presence in Cupertino since 1977, but it only recently opened its grand Apple Park campus to the public in 2017 -- MSN

Last month (2017年9月), Apple unveiled its highly anticipated — and highly expensive — new campus, Apple Park. The campus was designed by architecture firm Foster + Partners, covers 2.8 million square feet and accommodates 12,000 employees. It reportedly cost $5 billion to build — that's about $1,785 per square foot and $12.40 per square inch.
