The history of Weißenburg is generally traced back to the Roman fort that was built in the area towards the end of the first century. The settlement lay on the border of the Roman Empire and on the Tabula Peutingeriana from the 4th century it had the name Biriciana. Germanic tribes destroyed the fort and settled in what is still the city centre. The first mention of the name Weißenburg is in a deed dating from 867. The city became the seat of a royal residence during the reign of the Franks and according to legend, Charlemagne stayed there to supervise the construction of Fossa Carolina.
The Free Imperial City of Weißenburg

The city became a Free Imperial City in 1296 and continued to grow until the Reformation. Following the example of Nuremberg the city joined the Protestant side but it suffered heavily in the ensuing wars. However, the rights of the city as a Free Imperial City and an Imperial Estate were restored in the final peace treaty and some growth resumed. Despite its insignificant size and economic importance, the city, like the other 50-odd free imperial cities, was virtually independent.
Weißenburg lost its independence in 1802 and became part of the Bavarian kingdom in 1806. It was however saved from insignificance with the construction of a railway between Nuremberg and Augsburg which goes through the city and which supported industrialisation. Following World War II over 6,000 refugees and people expelled from the territories which Germany lost settled in the city and have since played an important role in its industry and culture.
The many stages in the history of Weißenburg can still be seen today. There are many ruins from the Roman times. One of the finest is the remains of a Roman bath was excavated in 1977 and has been turned into a museum. The city wall from the Middle Ages has survived almost intact with its towers and in the Gothic Town Hall the city's elected members have held their meetings from 1476.
Wülzburg is a historical fortress about 2 kilometres (1.2 mi) east of the center of Weißenburg. It stands on a hill 200 metres (660 ft) above Weißenburg, at an elevation of 630.5 metres (2,069 ft), and was originally a Benedictine monastery dating from the 11th century. It was converted into a fortress from 1588 to 1605 and is one of the best-preserved Renaissance fortresses in Germany. Today it is part of the city of Weißenburg.
The Nazis used it as a prison camp during the war; it was here that the Czech composer Erwin Schulhoff was held for over a year before he died of TB.
