From the plaque:
This building, constructed
in 1867 by the San Francisco and San Jose Railroad Company,
is the oldest railroad passenger station in California.
The Victorian ornamentation was added in the 1890's when
the station was remodelled to serve the newly-opened Stanford
University. The extension on the northwest was added to
accommodate increased traffic generated by the establishment
of Camp Fremont nearby during World War I.
Plaque placed by the State Department of Parks and Recreation in cooperation with the City of Menlo Park, July 4, 1983.
