Woodstock Square Historic District

Why it's listed
Woodstock's town square and the blocks around it form the historic heart of this northern Illinois county seat. The district covers about 13 acres and 73 buildings, including the 1857 Italianate courthouse designed by John M. Van Osdel, the 1887 jail, the 1889 Romanesque opera house, a 1906 high school now serving as city hall, and a 1931 post office. Around them stand two- and three-story brick commercial blocks, mostly Italianate-derived, with a Queen Anne block and plainer buildings from the 1910s and 1920s. A department store was added in 1928. Woodstock grew to serve nearby farms rather than as a regional center, and little development pressure meant buildings tended to survive except where fire removed them. The commercial area is essentially as complete as it was in 1912. The nomination values the buildings chiefly as a cohesive group, with recent restorations reversing many mid-century remodellings. The square retains brick-paved streets and a park replanted after a 1967 tornado.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
