Also known as the Dousman Mansion, Villa Louis is a National Historic Landmark in St. Feriole Island, Prairie du Chien, Wisconsin. It was constructed in 1871 in a Victorian architecture motif.

The Dousman family owned the estate until the early years of the 1900s. They even leased it out for different purposes until it was restored by two Dousman daughters and then passed on to the city government. It was later on acquired by the Wisconsin Historical Society, serving as the group?s first historical site.

Villa Louis now operates as a house museum after being restored to its late 1800s appearance. It is also a very popular wedding venue, mostly due to its romantic air and surroundings. Other events are also held on the site.
