All Saints' Church, commonly referred to as Schlosskirche (Castle Church)
On the occasion of the fourth centenary of Luther's birth in 1883, an extensive restoration of All Saints' in a Neo-Gothic style was begun under the supervision of the Prussian architect Friedrich Adler by his disciple Paul Ferdinand Groth (1859-1955).
The interior redesign included the present rib vault ceiling and pilasters, as well as matronea and the apse. Also, the 88-metre (289 ft)-tall steeple was rebuilt, from which one can obtain a good view of the city of Wittenberg and the surrounding countryside. A quote, "Ein feste Burg ist unser Gott" ("A Mighty Fortress Is Our God"), from one of Luther's hymns, encircles the tower.. -wiki
