Where was the viking film valhalla rising shot?

Valhalla Rising, a 2009 English-language Danish period adventure film directed by Nicolas Winding Refn, was shot entirely in Scotland. The film follows a Norse warrior named One-Eye and a boy as they travel with Christian Crusaders in search of the Holy Land, set during the 12th century. Despite its critical reception and production value, the film had limited commercial success. The title references Kenneth Anger's films Scorpio Rising and Lucifer Rising, reimagined with a Viking theme.
