The Viking ship museum at Roskilde is fascinating, as are the replicas that sail on the fjord outside,
but the real Viking age experience was at the National Museum in Copenhagen. In Denmark the Iron Age goes up to 1050AD or so, which includes the entire Viking period. You have never seen such a cornucopia of objects. Makes you wonder how careless all those ancient Danes were, losing so much stuff, or how rich they were, to be able to afford to bury such costly objects with their dead. Or to acquire such wonderful foreign goodies from the Mediterranean world. And it’s all so brilliantly displayed and lit. All the text is in Danish and English, in equal size type. Astonishing volume of finds.
