The hospital church was initially a towerless, three-aisled late Gothic hall church with a single-nave long choir, which the master builder Aberlin Jörg (collegiate church, Leonhardskirche) had built between 1471 and 1493 for the Dominican Order. After the monastery was dissolved during the Reformation, a hospital was set up in the empty buildings. The church became a parish church of the collegiate parish and received a tower on the south side of the choir in the 17th century. Only a few pieces of the original furnishings have been preserved. These include the Sachsenheim Altar from 1489 and tombs from the 16th and 17th centuries. The choir stalls were set up in the Leonhardskirche after the Second World War.
In 1944 the building was badly damaged by bombs. After the war, only the choir and the tower were restored according to Rudolf Lempp's plans. The nave remained in ruins as a memorial against the war.
In the choir is the original of the crucifixion group from 1501 by Hans Seyfer, which decorated the square behind the Leonhard Church until before the war. There is a copy there today from 1976.
The composer Leonard Lechner is buried in the hospital church.
