The Historical Roots of Princeton University's Location

Princeton University's location in Princeton, New Jersey, is no accident of history but the result of deliberate choices made over two centuries ago. Established in 1746 as the College of New Jersey in Elizabeth, New Jersey, the institution faced early challenges with space and health concerns, prompting a move to Newark in 1747. By 1756, it settled permanently in Princeton, selected for its strategic central position in colonial New Jersey. Governor Jonathan Belcher strongly recommended the site, emphasizing its balance between northern and southern influences, ideal for a Presbyterian-led college training ministers and leaders.

Nassau Hall, completed that year and named after the royal House of Orange-Nassau, became the heart of the campus. This Georgian-style building housed everything from classrooms to dormitories and even served as the U.S. Capitol in 1783 when Congress met there briefly. The Battle of Princeton in 1777 left a cannonball scar on its walls, symbolizing the site's Revolutionary War significance. This central New Jersey spot, roughly equidistant from New York City and Philadelphia, fostered growth into one of America's premier Ivy League institutions.
