Iron Block, 205 East Wisconsin Avenue, Milwaukee, Milwaukee County, WI

Significance: The Iron Block is notable as one of Milwaukee's most prominent early commercial buildings. It is one of a small number of pre-Civil War structures remaining in the central business district and is the city's chief example of the use of cast-iron for a building's facade. The architect, George H. Johnson, was an English-born builder-architect who managed Daniel Badger's Architectural Iron Works company in New York.
