If you're on a short trip, it's best to stay overnight, it's worth it. Xanten is a pretty little town, with cafés where you can sit outside, small shops, lots of historic buildings and a wealth of history. In addition to the Romans, the Spanish were also here, and later the French, not always with good intentions. Then it went back and forth within the dukedoms and bishoprics. The city tours on offer are worthwhile, as is a visit to the cathedral. It is huge for this small town, which boasts two saints. St Norbert (who really existed!) once lived here, and St Victor, to whom the cathedral is dedicated, died here. Yet there’s another important historical hero who was – allegedly – born here in Xanten: Siegfried, the great protagonist from the Song of the Nibelungs. Right next to the cathedral, the Siegfried Museum commemorates this, providing an entertaining insight into the 2400 verses and devoting itself entirely to the 800-year-old work about Siegfried's death and Kriemhild's revenge.
