Old Main

Old Main is a university building on the California campus distinguished by classical architecture, symmetrical stone facades, tall columns, and rows of windows across its stories. The structure displays characteristics typical of early-era university buildings with carefully proportioned exterior elements and functional interior spaces.

The building was constructed during the early phase of the university's expansion and represents the foundational period of the campus. Its listing on the National Register of Historic Places acknowledges its role as one of the earliest surviving main structures of the institution.

The name Old Main reflects its origins as the original central building of the campus and remains a gathering place for academic activities and student life. Daily use by students and faculty for classes, meetings, and events shows how deeply this building is woven into the university's daily operations.

The building can be visited through scheduled guided tours that show both the exterior architecture and the interior spaces. It is advisable to check in advance which tours are available and what areas are open to visitors.

The building preserves its original architectural design while housing modern educational technology and equipment inside. This blend of historical structure and contemporary facilities demonstrates how older buildings adapt to meet current university needs.
