Trondheim is the third largest city in Norway in terms of population, after Oslo the capital and Bergen. It is roughly in the middle of Norway when you look at a map, at ... 63 degrees north latitude, yes.

As our friend Wiki explains in detail (https://en.wikipedia.org/wiki/Trondheim), the city is very old. It was founded by the viking king Olaf Tryggvason in 997 (it was then called 'Nidaros'). Today, Olaf stands at the top of a column erected on the central square of Trondheim (the 'Torg' square). The city is located at the mouth of the river 'Nidelva', on the coast of a very wide fjord, the 'trondheimsfjord'.
