Blau’s Four Mile House, also known as the Reitman House, is a historic property located on Four Mile Road in Camp Springs, Kentucky, a rural area of Campbell County, Kentucky. The house was constructed by Nicholas Reitman as part of a settlement built by German immigrants in the mid-19th Century. The structure was added to the United States National Register of Historic Places in 1983. The building is “significant as a distinctive example of German stone architecture and for its historical context within the commerce of Four Mile Creek.” (Kentucky Historic Resources Inventory)
