One of Scandinavia's oldest cities, Trondheim was the first capital of Norway, from AD 997 to 1380. Founded in 997 by Viking king Olav Tryggvason, it was first named Nidaros (still the name of the cathedral), a composite word referring to the city's location at the mouth of the Nidelva River. Today, it's Central Norway's largest (and Norway's third largest) city, with a population of 150,000. The wide streets of the historic city center remain lined with brightly painted wood houses and striking warehouses. But it's no historic relic: it's also the home to NTNU (Norwegian University of Science and Technology) and is Norway's technological capital.
