Marktplatz, or Market Square, in Wittenberg. In the background are the two towers of the Stadtkirche, also known as the St. Marienkirche, which is considered “the mother church of the Restoration.” Martin Luther preached in it, and it was the first place where the mass was said in the vernacular language (German, specifically) and where both wafer and wine were administered to the laity.
