Henry Lincoln - Bornholm

Bornholm

In 1993, Lincoln wrote and presented the four-episode TV-series The Secret which was produced and directed by Erling Haagensen. The series presented elements of Lincoln's lifelong research on Rennes-le-Château, such as an alleged link between the area and the painting Les Bergers d'Arcadie by 17th century painter Nicolas Poussin. In 2000, Lincoln collaborated with Haagensen to write The Templar's Secret Island, linking their mutual hypotheses about geometry being observed in the placement of medieval churches around both Rennes-le-Château and the Danish island of Bornholm. These speculative findings led them to allege that the Knights Templar had built the churches on Bornholm in a specific pattern, to be used as a series of medieval astronomical observatories.

Author Sharan Newman has noted that the history given in The Templar's Secret Island "is based on a few pieces of data and several assumptions that rely on inaccurate information", also adding that there are no records of Templar activity in Denmark.

Mainstream historians and specialists in medieval architecture believe that the four central-plan churches in Ny, Nylars, Ols and Østerlars in Bornholm were built as a result of the pilgrimages made by Sigurd I of Norway to the recaptured Jerusalem between 1107 and 1111. Sharan Newman commented, "The idea of building a church in the form of the Church of the Holy Sepulcher in Jerusalem wasn't new. A hundred years before the Templar order was founded, the Benedictine church at Saint-Bénigne at Dijon was built with a round nave in imitation of the Holy Sepulcher. Even the Hospitallers built round churches."
