See the sharp angle between sunrise and sunset (in July). Arendelle might be located around 63 degrees north latitude.

Sunrise & Sunset almost at the same direction is not Disney’s error. In fact, this is impressively accurate! Sun not always rises in the east nor sets in the west. It depends on geographic location and time in a year. In this case, Scandinavia in July, you’ll see sun rises in NE and sets in NW.

One can guess latitude of a location by observing the angle between sunrise and sunset directions The higher latitude, the sharper angle. Try and see by yourself at http://www.suncalc.net/
