Visible for miles around, the tower of Castle Church rises 88 metres from the ground as the most prominent landmark in Wittenberg. Rather inconspicuous by comparison is the castle beside it, from whose southern wing another tower extends. The building is closed off on its northern side by the world-famous Castle Church, where Martin Luther nailed his theses to the door on 31 October 1517.
Its current appearance can be attributed to restoration work undertaken between 1883 and 1892. The interior of the church was completely redecorated on the basis of historical drawings and the church tower was also added. Martin Luther and Philipp Melanchthon are both buried there.
