The land surrounding this spot was originally the farm of George and Mary Drohman, pioneer German settlers who came to the U.S. around 1846. From 1851 to 1906, another German-American family, Adolph and Mary Sigglekow and their two sons, tilled this land. This foundation marks the site of their log and half-timber farmhouse. An ancient European technique called wattle-and-daub, in which sticks were woven together and packed with mud, was used as the original insulation. The house was moved to Sauk County in 1989.
