Perhaps what is best illustrated in this row of buildings is that time moved on, and while yes, the town is famous for its French roots, Ste. Genevieve slowly became more German and American, and the housing styles reflected that.
These houses and stores are beautiful, but not particularly more French than they are in any other city in America, reflecting the prevailing styles all over the country.
But perhaps that is what makes the town special is that there is that French history that still exists, peaking out from the later years of habitation.
I know I have seen a Common Grounds coffee shop somewhere else.
