Pilgrimage to the “Vi” Center of Bulverket's Water Square

At the cusp of Norse – Christian landscape transformation and pilgrimage, one investigates a technical ability to survey across land and ice. Two existing large bisects (Norse “vis”) with vertexes at significant natural or prehistoric features, statistically compare with the likelihood of identical geometry created by random points. The Bulverket platform in Tingstäde Trask and stone church on shore create vi centered points to map three-point alignments with churches. Alignments from the Bulverket are separately tested against random phenomena statistically proving accurate, surveyed lines of churches. Thus, land surveyed azimuths to either of the vi centers or points in their systems might create the varied orientations of these churches, ranging from 14° north to 18° south of due east. At each church, pairs or triads of azimuths from other lat/long points create squares or parallelograms whose diagonals mathematically lie within one degree of church orientations. Geometric determination of church orientation may have begun with the sacred Bulverket platform square in 1130.
