Following Oslo and Bergen, Trondheim is Norway's third largest city. This city of 173,000 residents is located in the Trondheimfjord, about 70 kilometers from the open sea. At the edge of the old town are the two most important structures in Trondheim - the Archbishop's Palace built in the 12th century and the Nidaros Cathedral. All of the royal coronations still take place in this cathedral today. Munkholmen Island, located at the entrance to the harbor, is a popular destination for outings, particularly in the summer. There are numerous hiking opportunities in the environs around Trondheim. For example, well-marked trails lead into the Trollheimen Mountains south of Trondheim. Or maybe you'd rather try your luck at fishing the plentiful lakes in the Trøndelag region.
