The Catholic Parish and University Church St. Louis, called Ludwigskirche, in Munich is a monumental church in neo-romanesque style with the second-largest altar fresco of the world. The building, with its round arches called the Rundbogenstil, strongly influenced other church architecture, train stations and synagogues in both Germany and the United States.
The Ludwigskirche is situated in the northern part of the Ludwigstrasse and was built by the architect Friedrich von Gärtner from 1829 onwards. The patron was King Ludwig I of Bavaria. The facade with two steeples was constructed as balance to the Theatinerkirche, which stands diagonally opposite. The floor plan shows the church as a model to a three-aisled Byzantine basilica with the basic geometric figure of the cross of tau. The church is 60 m long and 20 m wide. The towers are 71 meters high and each equipped with six bells, which are named after patron saints of the family of King Ludwig. In the years 2007-2009 the church roof was re-covered in the originally planned mosaic decoration.
The frescoes of the church were created by Peter von Cornelius. They are perhaps one of the most important mural works of modern times. The large fresco of the Last Judgment (1836-1840), situated over the high altar, measures 62 ft in height by 38 ft in width. The frescoes of the Creator, the Nativity, and the Crucifixion are also on a large scale. But the work was rejected by the King, and Cornelius left Munich shortly afterward. The sculptue Four Evangelists with Jesus Christ was designed by Ludwig von Schwanthaler.
The church was the model for many other churches, such as the Altlerchenfelder Pfarrkirche in Vienna, and Richard Upjohn's Congregational Church of the Pilgrims (1844-1846), in Brooklyn, New York, the first of the Rundbogenstil in North America. This was followed by St. George's Episcopal Church in New York City by Charles Bresch, and the Bowdoin College Chapel in Brunswick, Maine.
 Burial place
