Well over a thousand years old, this magnificent city - once an independent territory among Germany's states - keeps its past alive and demands a quick tour by car. It was once ruled by its own Prince Bishop, and his seat of power can still be visited: Saint Paul's Cathedral, one of the most imposing in Germany, was restored after World War Two, including its famous 16th century astronomical clock. The town hall and the *Krameramtshaus *- a guild headquarters - played vital roles in the signing of the Peace of Westfalia, which ended the Thirty Years War, back in 1648. This era still colours Germany's culture, literature and identity, and a fascinating trail of connections around the area is worth discovering. After that, why not drive to the Prince Bishop's Castle and admire the city's famous botanical gardens? Car hire makes it easy to enjoy one of Germany's most historic cities.
