The design of directional signs around the summit of the Brocken , which is 1141.2  m above sea level , is called Brockenuhr . NHN highest mountain in the German Harz low mountain range . The mountain is located near Wernigerode in the Harz district of Saxony-Anhalt . The system was designed as a circular signpost - wind rose with a diameter of 30  m . Around an artificially erected central rock there are panels with the names of visual targets and points of the landscape and locations far outside the field of vision, as well as distance information.

layout

On the Brocken summit, six large granite stones were placed in the middle of the sign . The largest stone weighs 19  tons . He bears on a bronze tabular the inscription chunks 1,142  m , which includes a below the board mounted bronze height marking. The circle with a diameter of 30 m consists of 48 bronze panels, each 0.5 by 1.5 m, set evenly in the ground. The panels each have a name and a distance; the positioning of the boards shows the direction in which the named destination is located.

The following tables with distances in kilometers (km) are arranged clockwise :

The exact angular directions of the compass rose are shown by dots at the outer end of the boards. Two of the goals, the Inselsberg and the Hohen Hagen, have arrow-like triangles instead of the points. These two mountains and the Brocken formed the largest measurement triangle in the Gaussian land survey carried out by triangulation by Carl Friedrich Gauß from 1821 to 1825 . A memorial plaque on the Brocken reminds of this.

history

Earlier cartographic "Brocken clocks"

Brockenuhr, 1912

A cartographic version similar to today's Brockenuhr was created as early as 1835 when the then Brocken landlord Eduard Nehse published a lithograph of the Brocken, on which a "Brockenuhr" was depicted with information on visual destinations and points of the landscape and localities far beyond the field of vision. The cards sold by the Brockenwirt became known as "Brocken clocks". The distances were given with geographical miles . Around 1880 the so-called "Stoll'sche Brockenuhr" was published, which supplemented Nehse's representation and described the information in kilometers .

Height measurements and current design

After general access to the Brocken plateau was re-enabled in 1989, the withdrawal of the CIS troops, the dismantling of the military buildings and the renaturation of the summit, the summit also had to be redesigned, whereby the exact height of the Brocken as the highest Harz mountain played a role. A new measurement showed a height of 1140.8  m . This came as a surprise to the public. While altitudes of 1140  m were found in older maps, at least from the 1940s onwards the height was given as 1142  m , and that is how it was taught. A survey commissioned by the Prussian General Staff in 1849 indicated the height of the Brocken as 1140.091  m , but there was another Prussian measurement that indicated 1142.273  m . This measurement referred to the top of a stone pillar that was in the middle of a cliff pile at the Brocken summit. The cliffs were probably removed as early as the 19th century to allow the second-hand stores to be expanded. At least there were neither cliffs nor pillars after the withdrawal of the CIS troops. At a meeting of the interior ministers of Saxony-Anhalt, Thuringia and Lower Saxony , it was politically decided that the known height of 1142  m should be established as part of the design of the summit plateau. This should be implemented by setting up granite stones.

Several variants were discussed for the design. Hiking guides from the Harz Club advocated the erection of a large granite block. There were stones with a weight of 50 to 70 tons to choose from. However, since transport via the Brockenstrasse, which is only approved for 15 tons, was not possible and an approach by helicopter was too expensive, it was not implemented. It was therefore decided to set up several small stones.

  • Two scoreboards

The granite stones were fetched from the edge of the Hermannschaussee , a forest and hiking path north of the Brocken near the Stempelsbuche , and placed on the mountain top by a crane on August 26, 1997. The inauguration took place on October 3, 1997 and at the same time marked the end of the renaturation work on the summit. Ideas to decorate the stones with sculptures of dancing devils or witches were discarded. The set up granite blocks, however, tower over 1142  m . This height is therefore indicated with a marker. In more recent height information for the Brocken, however, it is no longer 1142  m , but the height of 1141.2  m determined in more recent measurements .

The selection of the destinations indicated on the Brockenuhr is basically based on the Brockenuhrs from Nehse and Stoll. From the almost 200 pieces of information in Stoll's Brockenuhr, 48 were selected. Gunter Karste from the administration of the Hochharz National Park , Benno Schmidt from the Harz Club Wernigerode and Roman Warnicke from the Harz Club in Schierke were particularly involved in designing the Brockenuhr .
