In the heart of the historic city of Prairie du Chien, on the picturesque St. Feriole Island, lies the magnificent Villa Louis. This is more than just a mansion; it is an entire historic site and a U.S. National Historic Landmark, considered one of the finest examples of Victorian Italianate architecture in the country.

Built in 1871 and designed by architect E. Townsend Mix, the villa was once the ancestral home of the influential Dousman family. Today, it is an open-air museum managed by the Wisconsin Historical Society. The 25-acre estate includes not only the luxurious main residence but also numerous outbuildings that transport guests back to the heyday of the fur trade and early American entrepreneurship.
The special value of Villa Louis lies in its striking authenticity. Thanks to meticulous restoration, the house looks exactly as it did in the late 19th century. Inside, you'll find not only original furniture and decor but also cutting-edge amenities for its time—such as a steam heating system and indoor plumbing—making the complex a unique monument to the technical progress of the Victorian era.
