Templar churches on Bornholm Island, Denmark
Located 40 kilometers southeast of the southern tip of Sweden but territorially part of Denmark, the island of Bornholm is one of the oldest visible rocks in the world....Archaeological excavation reveals the island to have been settled since at least 3600 BC, when numerous dolmens and Neolithic mounds began to be constructed....
In medieval times, the island was known as Burgunderland or Burgunderholm, from which the present name derives (holm is an old Danish word for island). During the transition to Christianity between 1050 and 1150 AD, around 40 runic stones were erected around the island and today most of these are found in the vicinity of churches and old bridges where they have often been reused as building materials.
Clearly the most famous of the ancient constructions of Bornholm Island are its medieval round churches. The current hypothesis among historians is that these structures were not intended solely for religious practices but that they also had a defensive function. Given their assumed construction period in the 12th century, this makes seems to make sense as the Baltic region was then subjected to near continuous raids by Slavonic pirates from the island of Rugen, off the German coast. (...) (However), if places of refuge were needed during times of attack, it would have been far more logical for the population to have gathered within the fortresses of Gamleborg and Lilleborg, which were vastly more secure and defensible during the time of the supposed pirate raids.
Writing in their book The Templars' Secret Island: The Knights, The Priest And The Treasure, Erling Haagensen and Henry Lincoln present evidence linking the four round churches of Bornholm with the controversial and much misunderstood religious brotherhood of the Templars. (...) Haagensen and Lincoln have done pioneering work in the analysis of Bornholm's sacred geography but the authors believe that deeper and more esoteric secrets remain to be discovered. The celestial alignments of the island's Neolithic constructions and the round churches need to be studied in more detail (for example the upper windows in the Osterlars church were positioned to be in alignment with the sunrises of the winter and summer solstices). Additionally, ancient pagan symbols encoded in carvings and frescos found in the four round churches and also at Poulsker church in south Bornholm need to be examined with a broader knowledge than that of the conventional historical approach.
