No part of Western Europe is crossed by the Arctic Circ

Explanation:

The Arctic Circle represents the southern limit of the polar day. Anywhere north of it, the sun can be seen above the horizon for more than 24 hours, at least once a year.

Also, north of the circ, it happens at least once a year that light is not visible above the horizon for at least 24 hours. The Arctic circ is characterized by a very cold and difficult climate, so it is sparsely populated.

Arctic circle crosses the Atlantic ocean, the Scandinavian peninsula, North Asia, North America, and Greenland.

In the Arctic circ, there are 8 countries: Norway, Sweden, Finland, Russia, USA (Alaska), Canada, Denmark, Island.
