When in Norway, pay your homage in the Nidaros Cathedral, the largest building that dates back to medieval ages, which is located in Trodenheim, Norway. It has the relics, of the Norwegian Emperor St. Olav, preserved in a very good condition. Or visit the Urnes Stave Church, in Western part of Norway which has its history that dates back to 1130 and also it’s recognized by UNESCO as a World Heritage Site.  Or when you’re holidaying in Denmark, visit the Cathedral of Roskilde near Copenhagen. Dating back to the 12th Century, the Rosklide Domkirke, was established by Absalon, and also used as a royal mausoleum. UNESCO declared this site as the World Heritage Site in 1995. Don’t forget to visit the Gamla Uppsala, in Sweden which is a ceremonial site of much importance. A pagan temple was destroyed and a Swedish Curch was built above that ground which hosted regular sacrifices and was also a burial ground for the royalty.
