Old Main, California State College

Why it's listed
Old Main is a brick building with a dressed blue sandstone foundation, built in 1868-1870 in a cruciform plan and designed by Barr and Moser of Pittsburgh. Its main wing has a central entrance with a verandah of semicircular arches on Corinthian columns, flanked by two towers roughly 90 feet high with pyramidal roofs of variegated slate. The second floor holds a chapel seating 1000 people. Upon completion it housed offices, classrooms, a chapel and a dormitory for South-Western Normal College, which later became California State College. The building served as the college's main administration building from 1870 until 1971. It is regarded as a fine example of Romanesque Revival architecture, a style rarely seen in southwestern Pennsylvania. Its significance rests on that architecture and on its long role in education. Alterations include an 1899 verandah addition and the 1968-1969 removal of the northeast section of the main wing, which left the building T-shaped.
Significance in brief: The nomination argues that Old Main is significant for its architecture, as a fine example of Romanesque Revival style that is rarely found in southwestern Pennsylvania. It also cites its long role as a center of education, from its use by South-Western Normal College through its service to California State College.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
