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,[1] the act that has been called the start of the Protestant Reformation.[2][3] From 1883 onwards, the church was restored as a memorial site[4][5][6] and re-inaugurated on 31 October 1892, 375 years after Luther’s posting.
