Protestantism was born in the little town of Wittenberg (officially called Lutherstadt-Wittenberg). In 1508 the fervently idealistic young Martin Luther, who had become a priest only a year earlier, arrived to study and teach at the new university founded by Elector Frederick the Wise. Nine years later, enraged that the Roman Catholic Church was pardoning sins through the sale of indulgences, Luther attacked the policy by posting his 95 Theses on the door of the Schlosskirche (Castle Church).
Martin Luther is still the center of attention in Wittenberg, and sites associated with him are marked with plaques and signs. You can see virtually all of historic Wittenberg on a 2-km (1-mile) stretch of Collegienstrasse and Schlossstrasse that begins at the railroad tracks and ends at the Schlosskirche.
In preparation for the 500th anniversary of the Reformation, much of the city will be under massive reconstruction until the summer of 2017. The Lutherhaus and the Schlosskirche are only accessible on special occasions during construction.
