Step inside the historic 1841 Foster House on the first Saturday of the month from May to October to see how 19th century Fort Atkinson residents lived, and learn about how the community grew. A friendly guide will be available to answer questions and show visitors around the first and second floor of the house.Built in 1841 for the sum of $2,000, the Foster House was the first frame house constructed in Jefferson County.Dwight and Almira Foster were the first permanent non-Indian settlers in Fort Atkinson, arriving in November 1836, with their young daughter, Celeste. After four years in their rustic log cabin near the banks of the Rock River, the Fosters moved into this frame house built by fellow pioneer, Charles Rockwell. This two-story, five-room home, with window glass shipped from New York via the Erie Canal, was the first frame structure in the community.
