Trondheim:
is a city and municipality in the county of Sør-Trøndelag, Norway. Founded in 997, Trondheim is today a centre of education, technical and medical research, with 30 000 students, and is the third largest city in the country. Two of Norway's greatest tourist attractions are the Nidaros Cathedral and Archbishop's Palace. They are located side by side, in the middle of historic Trondheim. The large gothic cathedral, built from 1070 on, was Northern Europe's most important Christian pilgrimage site during the middle ages, with pilgrimage routes from Oslo in southern Norway, and from the Jämtland and Värmland regions of neighbouring Sweden. The city is also known for its active winter sports scene, with cross-country skiing tracks in Bymarka and a ski jumping arena in Granåsen, as well as nearby alpine skiing facilities at Vassfjellet.
