At which university was House M.D.'s fictional Princeton-Plainsboro hospital exterior filmed?

The exterior used for House M.D.'s fictional Princeton-Plainsboro hospital was filmed at Princeton University.

The series presents Princeton-Plainsboro Teaching Hospital as a New Jersey medical center, but the recognizable exterior is largely Princeton University's Frist Campus Center in Princeton, New Jersey. This location helped make the fictional hospital visually convincing while connecting the production to the setting suggested by its name.

Most interior scenes and many other locations were filmed in California, especially around Los Angeles. The contrast between the New Jersey setting and California production locations is a common behind-the-scenes detail associated with the series.

The hospital should not be confused with a real institution called Princeton-Plainsboro Teaching Hospital. It is fictional, even though the production used real university architecture. Yale, Stanford, and Columbia are prominent universities with medical schools, but none supplied the principal exterior associated with the show.
