Delaware County Courthouse Square District
Why it's listed
Delhi's courthouse square is a compact grouping of 19th century government, commercial and religious buildings arranged around an open village green. The two and a half story red brick courthouse dominates the space, with a mansard slate roof, a four story entrance tower, elaborate dormers and ornate brickwork. Isaac G. Perry designed it after county supervisors voted in 1868 to replace an earlier wood frame courthouse, and local voters pledged funds to keep the county seat in Delhi. Nearby stand the sheriff's office and jail, a bandstand, a former courthouse now used as village offices and a fire hall, and a church and bank designed by Charles Hathaway in 1831 and 1838. Surrounding commercial buildings are mostly two or three story clapboard structures. The district is valued as a typical small town courthouse square whose architectural integrity has been remarkably preserved, reflecting the village's growth and its long role as county seat.
Significance in brief: The district is presented as a well-preserved example of a small-town courthouse square that was the center of county and village life. It is notable for the architectural integrity of its buildings and for reflecting the village's 19th century growth and long service as county seat. The 1868 brick courthouse, designed by Isaac G. Perry, anchors the group.

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).
