Wisconsin's and the nation's largest Belgian American settlement lies in parts of Brown, Kewaunee, and Door counties along Green Bay. Walloon-speaking Belgians settled the region in the 1850s and still make up a high proportion of the population. Their presence appears in place names such as Brussels, Namur, Rosiere, and Luxemburg, in a local French patois, in common surnames, in distinctive foods including boohyah, trippe, and jutt, in the Kermiss harvest festival, and especially in architecture. Many of the original wooden buildings were destroyed in a firestorm that swept across southern Door County in October 1871, but a few stone houses of local dolomite survived. More common are red brick houses from the 1880s, marked by modest size, gable-end bull's-eye windows, and sometimes detached summer kitchens with bake ovens at the rear. Many of the Belgians were devout Catholics and also built small roadside votive chapels like those in their homeland.
