Østerlars Round Church

Østerlars Rundkirke is not only the largest round church on Bornholm, but in all of Denmark. It is also believed to be the oldest of Bornholm's four round churches, although the exact year of construction is unknown. Østerlars Rundkirke is central to the theory that there is a connection between the French Order of the Knights Templar and the location of Bornholm's medieval churches.
