Christuskirche, Lutheran church in Altstadt, Salzburg, Austria

Christuskirche is a free-standing historicist brick church framed in cast stone and Untersberg conglomerate, combining Neo-Gothic and Neo-Romanesque elements. Its main portal faces the Salzach at Elisabethkai, with a richly articulated facade tower topped by an octagonal bell storey and pointed tent roof. The plain nave has an open hammer-beam roof in English Gothic style, wooden galleries on three sides, and a polygonal apse.

Construction of the church began in 1863 with help from Danish prisoners of war and was completed in 1867. It became the first Protestant church built in Salzburg following the earlier expulsion of Lutherans from the region.

Two 1868 canvas paintings by the Weimar history painter Friedrich Martersteig hang in the church: one shows the 1731 oath of loyalty of the Salzburg exiles, the other their departure from Salzburg. A third Martersteig painting commemorates the consecration and includes the painter himself among the figures.

The main portal with its tower faces the Elisabethkai, open toward the Salzach, so the entrance is reached from the right bank of the river in the right old town. The adjoining parish house and former school building on Schwarzstraße were built by Jacob Götz in 1868–1869. The interior keeps its original furnishings, though the original painted decoration is lost.

The organ, built in 1867 by Georg Friedrich Steinmeyer of Oettingen as his Opus 66, was the first instrument in Salzburg with cone chests. It was played at the consecration by Friedrich Samuel Riegel, organist of St. Matthäus in Munich. In 1884 Theodor Mann called it one of the best organs he had seen.
