the cathedral cloister was built in 1140 as a burial chapel for Bishop Hartwig II by a group of builders from Como in northern Italy. It consists of a trefoiled apse and a middle room with an octagonal drum and pavilon roof. Most of the valuable stained glass windows were installed between 1220–1230 and 1320–1370, and the windows of the west facade were only completed in the 19th century. Between 1967 and 1968, the windows of the left chancel, from the hand of the artist Professor Oberberger, were installed. He also produced the Pentecost window near the Northern transept and the clerestory windows in Gothic style. The cathedral opened in the year 1550. The silver high altar stems from Augsburg artists, and was built at some point between 1695 and 1785. Another particular feature are the five Gothic Altars of Reservation. In the southern choir a new Altar of Celebration was built in 2004, and it was the work of Helmut Langhammer. Significance Regensburg Cathedral is the bishop's church and the principal church of the Roman Catholic Diocese of Regensburg. It is also the home of Regensburger Domspatzen, which serves as the cathedral choir, and is rich in tradition. The structure is considered the most significant Gothic work in southern Germany. The cathedral is also the burial place of important bishops, including Johann Michael von Sailer (1829–1832, memorial built by Konrad Eberhard in the south chancel), Georg Michael Wittmann (1832–1833, memorial also by Konrad Eberhard in the north chancel), and Archbishop Michael Buchberger (1927–1961, likewise in the north chancel). In the western part of the central nave stands a bronze memorial for the Prince-Bishop Cardinal Philipp Wilhelm (d. 1598), the brother of Duke Maximilian I of Bavaria.
