Wittenberg is a university town along the River Elbe in eastern Germany, with close ties to Martin Luther, leader of the Protestant Reformation. The Lutherhaus, once a monastery and Luther’s home, is now a museum displaying his personal artifacts and paintings. On the city’s main plaza, Market Square, stands the 13th-century Stadtkirche where Luther preached, known as the Mother Church of the Reformation.
