Trunk The trunk of the lime tree has suffered significant hollowing, with much of it destroyed, leaving only a strongly inclined remnant. To support the remaining trunk and an almost horizontally projecting main branch, iron clamps, and threaded rods are used. Additional support is provided by several iron and wooden rods. Interestingly, an elder bush has taken root in the hollowed-out trunk and is growing outwards through an opening. The bark is covered with
mosses and
lichens in many areas, and the remaining parts of the crown are overgrown with
mistletoe. If fully preserved, the trunk would have a circumference of about 16 meters. However, in 1987, the trunk circumference measured 11.2 meters, and in the year 2009, it was just under eight meters. Measurements taken at the site of the smallest diameter showed a circumference of 4.6 meters. In 1990, the total height of the tree was recorded at 11 meters, with a crown diameter of 16 meters.
Age Due to the absence of the oldest wood from the center of the trunk, it is not possible to determine the lime tree's age accurately through methods such as annual ring counting or
radiocarbon dating. As a result, the actual age of the lime tree can only be roughly estimated. In 2008, a representative from the
Deutsche Baumarchiv (German Tree Archive) estimated its age to be between 600 and 800 years old. However, on several occasions, it has been speculated that the tree could be over 1000 years old. This would make the lime tree one of the ten oldest lime trees in Germany.
Location Kasberg is situated approximately three kilometers northwest of Gräfenberg and about 25 kilometers northeast of
Nuremberg. The lime tree is located on the western edge of the village at an elevation of approximately 510 meters
above sea level. It stands next to the intersection of two old traffic routes: the road between
Leutenbach and Gräfenberg (today FO 14) and the road between Walkersbrunn and Kasberg (FO 42/FO 14). The area is part of the
Franconian Switzerland region within the
Franconian Alb, characterized by a plateau landscape on its southwestern edge. The soil surrounding the lime tree consists of
calcareous, loamy weathering material from the
White Jurassic period. == History ==
