Steinvikholm Castle is an island fortress on the Skatval peninsula near Stjørdal, in Nord-Trøndelag county, Norway. The castle was built over seven years, from 1525 to 1532, by Norway’s last Catholic archbishop, Olav Engelbrektsson. Steinvikholm castle became the most powerful fortification by the time it was built, and it is the largest construction raised in the Norwegian Middle Ages.

Thank you Hallvor! It’s a beautiful and spooky view.

What causes the aurora borealis or northern lights?
