Denhart Bank Building
Also known as: Anthony and Denhart Bankers

Why it's listed
Standing at the northwest corner of Washington Square in Washington, Illinois, this two-story brick building began as an Italianate bank built around 1872. Its rose-colored brick walls, sandstone window crowns with keystones, limestone sills and canted corner entrance mark it as a good local example of the style. Between 1902 and 1908 Henry Denhart bought the adjoining Colonial Revival-influenced building to the north and combined the two into an L-shaped structure. The bank began as Anthony and Denhart, became Henry Denhart and Company in 1885, and financed farm and town growth across Illinois and other Midwestern states until the state closed it in 1930. Depositors recovered only part of their money, and the failure affected property owners in many counties. Inside, the vault, safe, oak counter and much original woodwork survive. The upper floor was converted to apartments in 1951, and restoration work, including a replica cornice, was underway at the time of listing.
Significance in brief: It is locally significant for its association with banking in Washington, from the Anthony and Denhart partnership through Henry Denhart and Company, which failed in 1930. It is also a good local example of Italianate architecture.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
