Nördlingen is a small, historic town in the German state of Bavaria that’s well worth a visit. The town is dominated by its impressive 14th century city wall, which is one of the best preserved in Germany, and the old town centre is a maze of narrow streets and squares lined with half-timbered houses. There are a few interesting museums, including the Rieskrater Museum, which tells the story of the impact crater that formed here some 15 million years ago, and the Deutsche Klingenmuseum, which is dedicated to the art of knife-making. Nördlingen is also famous for its annual Riesenkuchen (giant cake), a huge pastry that’s over 2 metres in diameter and weighs almost 400 kg.
