Orange Union High School
Also known as: Chapman College
Why it's listed
Five neo-classical buildings on North Glassell Street in downtown Orange formed Orange Union High School and now make up the heart of the Chapman College campus. Wilkinson Hall, the oldest, was completed in 1904 and later moved about 300 feet. The Old Science and Education/Art buildings date from 1913, Memorial Hall from 1921 with a music hall added in 1926, and Founder's Hall from 1928. Four buildings surround a tree-lined quadrangle, and the exteriors feature simulated rusticated stone bases, painted plaster walls, cornices and pedimented entrances. Memorial Hall holds an auditorium seating about 1,000, long the largest of its type in the county. The nomination presents the school as a community cultural center, supported by local bonds and donations after an agricultural blight in the 1880s. Chapman College moved onto the site in 1954 and continued the tradition with concerts, lectures, art and film programs. Its World Campus Afloat program carried the Orange address internationally.
Significance in brief: The nomination argues that the buildings served as the cultural center of Orange for decades, first as the high school and then as Chapman College. It points to the 1921 auditorium, the community's investment in education, and the college's lectures, arts programs and international study programs. It also cites the architectural rarity and good maintenance of the buildings.

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.
