Located in upper Bavaria the city of Regensburg has a long and rich history that actually dates back to the Stone Age. The oldest settlement in the region is near the modern day city, and this was likely founded by the Celtic tribes in the region at least 1,000 years before the Romans arrived. Situated on the northern “Germanic” frontier the area was largely ignored during the expansion of the Roman Republic, but at the end of the 1st century the Romans built a fortified outpost. This was near the previous Celtic settlement of Radasbona, as it was called by its inhabitants. During the next 100 years the area grew in importance, and a town grew near the Roman fort of Castra Regina.

Following the decline and fall of the Roman Empire in the west the area was home to various German tribes, most notably the Bayuvaren peoples, who became known as the Bavarians. The city of Regensburg was the capital of Bavaria from the 6th to the 13th century, and the city was part of a prosperous trade route between Northern Europe and Italy. As a result the city became a cultural center in what is today modern Germany.

The city and region part of the Bavarian duchy during the Middle Ages, and part of the Holy Roman Empire. The city became the permanent seat of Reichstag of the Holy Roman Empire from 1663 until the empire was dissolved by Napoleon in the early 19th century. It remained an important Bavarian city for the next 70 years, until the unification of Germany in 1871.

Unlike many other German cities, Regensburg suffered little damage during World War II, and was named a UNESCO world heritage site. Today it retains most of its Medieval storybook style houses that is typical of Bavaria.
