Kath. Kirchenstiftung St. Ludwig
The Catholic parish and university church of St Ludwig was consecrated in 1844 and still has the second largest altar fresco in the world. The large organ was built in 1960 on the initiative of the long-standing church musician and diocesan music director Rudolf Thomas by the Hamburg company Rudolph v. Beckerath. To this day, it is one of the most important and beautiful-sounding organs in southern Germany.
