Western end of College Street looking toward the Castle Church in Wittenberg, Germany. Luther walked down this street to post his 95 theses on the Castle Church door on October 31, 1517, setting in motion the events that would come to be known as the Reformation.

The Castle Church itself was completely gutted in the Thirty Years War. It was part of the Elector's Castle complex in Wittenberg. The tower that now appears was rebuilt by the Prussian Emperor in the 19th century, who turned the Castle Church into a shrine to the Reformation, both Lutheran and Reformed.

The interior of the church is not original to the period, like the majority of things seen there. What is authentic is the Luther grave, and the statues of the two Saxon Electors who are buried before the altar in the church. In the rear of the church are ancient Medieval graves of certain Wettin family members, the ancient rulers of Saxony. All along the outside of the church are grave markers and memorials, many heavily weathered and eroded.

During the days of Communism, the town of Wittenberg was permitted to fall into near ruin. During World War II the American bomber command made sure that the city center of Wittenberg was not targeted, although factories near the city were. Fortunately, many of the important buildings were spared heavy damage.
