I saw der Xantener St. Viktor Dom back in December when we took an evening trip to Xanten. It's a…read morebeautiful cathedral. I only saw the inside and it was in the winter and at night, but I would love to come back in spring or summer during the day when the gardens are in bloom and it's bright out, as well as when it's open so I can go inside too. This city didn't have any tourists from what I could see at the time so it was definitely good if you want to experience a small German city with not a lot of English influence. It's located not too far from Köln in Nordrhein Westphalia.
