This is a complete tower with a roof, built in the 10th or 11th century and 27.5 meters in height - with a base diameter of 4.04 meters. The doorstep is 3.9 meters above ground. Unusual, not to say unique, is the "stairway" leading up to the door. It is also an extremely slender tower ... and the profile shows a concave irregularity.
