The unexpected “swaying” of eastern part of church was
recorded (i.e. the movements of whole church block had
alterative directions). This has been confirmed by independent
records in horizontal and vertical tilt meters on neighbouring
east and south wall, also accompanied with relative closing or
opening of cracks.
The ground water levels were not measured in the same
frequency, but the collected data indicate possible correlation of
seasonal variations of water levels with the directions of wall
movements.
