Building Cal Poly: A Historical Look Back

Special Collections and Archives > University Archives > Building Cal Poly

Place has always been central to Cal Poly’s identity. Since the first 281 acres of ranch lands were purchased in 1902, Cal Poly’s mission and signature learn-by-doing philosophy have shaped the campus and the facilities that support its educational programs.

In its over 100-year history, Cal Poly has never been a fixed landscape. Through the actions of administrators, students, faculty, alumni and the broader community, the campus has constantly evolved, expanding to over 10,000 acres today.

Records from the University Archives capture the opportunities, challenges, and decisions that shaped the development of campus. The archives bridge time, revealing that all students share common spaces and experiences. The records reveal tension between preserving the historical campus while planning for a future that not only reflects but also produces innovation. By exploring this history, we can recognize the central role of the land and the built environment in constructing Cal Poly’s unique identity.
