Old Main, Knox College
Why it's listed
Old Main, the oldest building on the Knox College campus in Galesburg, Illinois, was designed by Peoria architect Charles Ulricson and completed in July 1857. Built in a Tudor Gothic manner modeled on parts of Hampton Court Palace, it is a square, three-story structure of rose brick and limestone with crenelated towers, mullioned windows and a white wooden belfry. On October 7, 1858, it was the setting for the fifth Lincoln-Douglas debate. A platform stretched across the east facade, and about 15,000 people listened from the lawn. Lincoln argued there that slavery was a moral issue, and a banner read 'Knox College for Lincoln.' The building decayed by the 1930s and was restored from 1933 to 1938, with a new concrete and steel interior inside the old brick walls. A 1969 tornado removed part of the roof and the belfry, which were later rebuilt. Today it holds offices and classrooms. It is regarded as the best-preserved debate site.
Significance in brief: Old Main and the adjoining grounds are described as the best-preserved site associated with the 1858 Lincoln-Douglas debates. The fifth debate took place on October 7, 1858, from a platform built across the east facade, before an estimated 15,000 people. Lincoln spoke there of slavery as a moral issue, and the college openly backed him.

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.
