Die Altstadt in Straubing, Bayern, Southern Germany. In August, the Gäubodenvolksfest, the 2nd-largest fair in Bavaria, is held here. The area has been continuously settled since the Neolithic. The conquest by the Romans in 16–14 BC had a dramatic impact on the region. Even today many traces of the 400-year Roman occupation can be found: for example, the famous Römerschatz (Roman treasure) which is shown in the Gäubodenmuseum. After the fall of the Roman Empire, it became a centre of settlement of the Bavarii. According to their customs, the settlement was named after their leader Strupinga, which later evolved into the name Straubing. In 1218 a new part of the city was founded by Duke Ludwig I Wittelsbach of Bavaria.
