At the crossroads (CR-DK and CR-N in Door County) known as Namur, Historic Marker 321 tells you all about early Belgian settlement in Wisconsin. (Namur is about 2 miles west of Brussels.) The firestorm mentioned on this marker is the Peshtigo Fire which Historic Marker 1 commemorates.
Here are closeups of the smaller plaques on the left and right of the main marker.
St. Mary of the Snows Cemetery is a very compact plot of land several yards behind the historic marker.
The church building (below, formerly St. Mary of the Snows) to the left of the marker and cemetery (along with other buildings in the area) are part of the Belgian Heritage Center. the Center doesn’t open until Memorial Day, so we couldn’t go inside on this visit.
As noted on the plaque above, this is all part of a National Historic Landmark.
