In the town of Bamberg, in Upper Franconia, Bavaria, Germany

 The German town of Bamberg has been a UNESCO World Heritage Site since 1993.

===================================================================
Bamberg extends over seven hills, each crowned by a church. A town in the Upper Franconia district of Bavaria, on the Regnitz River; it dates back to the 9th century, when its name was derived from the nearby Babenberch castle. After a communist uprising took control of Bavaria in the years following WWI, the state government fled to Bamberg and stayed for almost two years before the Bavarian capital of Munich was retaken by Freikorps units. After WWII, Bamberg was a base for the Bavarian, German, and then American military stationed at Warner Barracks, until 2014.

During the post-Roman centuries of Germanic migration and settlement, the region encompassed by the Diocese of Bamberg was predominantly inhabited by Slavs. The town, first mentioned in 902, grew up by the castle Babenberch, which gave its name to the Babenberg family. The area was Christianized by the monks of the Benedictine Fulda Abbey, and the land was under the authority of the Diocese of Würzburg. In 1007, the Holy Roman Emperor Henry II made Bamberg a family inheritance, the seat of a separate diocese. His purpose was to make the Diocese of Würzburg less unwieldy, to give Christianity a footing in the districts of Franconia, east of Bamberg. In 1008, the boundaries of the new diocese were defined, and Pope John XVIII granted the papal confirmation in the same year. Henry II ordered the building of a new cathedral, which was consecrated on 6 May 1012. The church was enriched with gifts from the pope, and Henry had it dedicated in his honor. In 1017, Henry founded Michaelsberg Abbey on the "Mount St Michael," near Bamberg, a Benedictine abbey for the training of the clergy. The emperor and his wife gave large temporal possessions to the new diocese, and it received privileges out of which grew the secular power of the bishop. Pope Benedict VIII visited Bamberg in 1020 to meet Henry II for discussions about the Holy Roman Empire. While he was there he placed the diocese into dependence on the Holy See. For a time, Bamberg was the center of the Holy Roman Empire.

+ From the middle of the 13th century onwards, the bishops ruled Bamberg. In 1248 and 1260, the see gained parts of a territory extending from Schlüsselfeld in a northeast direction to the Franconian Forest, and possessed estates in the Duchies of Carinthia and Salzburg, in the present Upper Palatinate, in Thuringia, and on the Danube. As a result of the Reformation, the territory of this see was reduced by nearly 50%. In 1647, the University of Bamberg was founded. The possessions of the diocese in Austria were sold to that state. Bamberg thus lost its independence in 1802, becoming part of Bavaria in 1803.

After a communist uprising took control over Bavaria in the years after World War I, the state government fled to Bamberg for nearly two years before the Bavarian capital of Munich was retaken by Freikorps units.
