All Saints' Church, commonly referred to as Schlosskirche (Castle Church) to distinguish it from the Stadtkirche (Town Church) of St. Mary's – and sometimes known as the Reformation Memorial Church – is a Lutheran church in Wittenberg, Germany. It is the site where the Ninety-five Theses were likely posted by Martin Luther in 1517, the act that has been called the start of the Protestant Reformation. From 1883 onwards, the church was restored as a memorial site and re-inaugurated on 31 October 1892, 375 years after Luther's posting.
When in the late 15th century the Wettin prince Frederick III the Wise, elector of Saxony from 1486, had the former Ascanian fortress rebuilt, a new All Saints' Church was designed by the architect Conrad Pflüger[4] (c. 1450 – 1506/07) and erected between 1490 and 1511 in the Late Gothic style. Consecrated on 17 January 1503, it became part of Frederick's electoral castle or Residenzschloss, also called Schloss Wittenberg. Extensive furnishings by Tilman Riemenschneider, Jacopo de' Barbari, and Albrecht Dürer contributed to the construction of the castle complex and then the church.
The main portal was often used by the university staff to pin up messages and notices; it is generally believed that on 31 October 1517, the eve of All Saints' Day, Martin Luther posted his Ninety-five Theses on the doors of All Saints' Church. This act, meant to promote a disputation on the sale of indulgences, is commonly viewed to be a catalyst for the Protestant Reformation. If the event has actually taken place or not, however, could not be conclusively established. Nevertheless, Luther sent his objections in a letter to Archbishop Albert of Mainz on the same day.

Frederick the Wise died in 1525 and was buried in the Castle Church. In the same year, the Lutheran rite was implemented. The church became the burial site of Martin Luther himself in 1546, and of Philipp Melanchthon in 1560.
