The Bruchhauser stones are a rock formation with four main rocks at 728  m above sea level. NHN high Istenberg in the Rothaar Mountains . They are located near Bruchhausen in the North Rhine-Westphalian Hochsauerlandkreis .

The rocky landscape is designated as a ground monument , a nature reserve , fauna-flora-habitat , bird sanctuary and national natural monument . The rocks have also been recognized as a national geotope and, as an element of geological heritage that is worth protecting, they are part of the National GeoPark GrenzWelten .

The highest rock, the Bornstein , is 92 m high. The Bruchhauser Steine ​​Wallburg used to be between the four main rocks .

geography

location

The Bruchhauser stones rise up in the northern part of the Rothaargebirge on the northwest slope of the 728  m high Istenberges , the east of the origin of the Ruhr -Zuflusses Gierskoppbach located Bruchhausen lies a village district of Olsberg . The rocks are on average about 600 m from the mountain top.

Natural allocation

The Bruchhauser stones belong as part of the Istenberg in the natural spatial main unit group Süderbergland (No. 33), in the main unit Rothaargebirge (with Hochsauerland ) (333) and in the subunit Hochsauerländer Schluchtgebirge (333.8) to the natural area Schellhorn and Treiswald (333.82), in which they form a 4th to 7th order singularity . The landscape descends in western directions into the natural area Bödefelder Mulde (with Assinghauser Grund) (333.80).

The four stones

The four main rocks of the Bruchhauser Stones are called - with rock height in meters (m), height in meters (m) above sea ​​level (NHN) and area in square meters (m²):

Bornstein

The Bornstein (in the north-northeast) is the highest of the four rocks with a rock height of about 92 m. Its summit is around 700  m above sea level. The base of the rock is about 5,000 m². Its name is probably derived from a spring that used to exist on the summit (Born = spring). The rock is the preferred breeding ground for the peregrine falcon.

Field stone

The field stone (in the south-southwest) has a rock height of about 45 m. Its summit is around 756  m above sea level. The rock has an area of ​​around 2,000 m². Its name is probably derived from field (field = wide level). The field stone is the only one of the four stones that can be climbed - on the Thomas-Neiss-Steige . Its summit, on which a 9 m high wooden cross stands, towers 28 m above the Istenberg summit. A trigonometric point is located southeast below the rock summit at a height of 727.2  m .

Goldstein

The Goldstein (in the east) is about 60 m high. Its summit is around 712  m above sea level. The rock has an area of ​​around 2,000 m². Its name probably comes from the golden shimmering quartz inclusions in the rock. On the eastern flank of the Goldstein is the stone formation Great Elector , whose profile (with a lot of imagination) resembles the head of the Great Elector .

Ravenstein

The Ravenstein (in the west) is about 72 m high. Its summit is around 701  m above sea level. It has a floor area of ​​around 2,200 m². Its name probably comes from Rabenstein, the stone of the corvids.

geology

The Bruchhauser stones are made of porphyry and the basement is made of soft clay slate , which was formed around 370 million years ago in the Devonian period from deposits of a prehistoric sea. During later volcanism 290 million years ago, lava penetrated into crevices of this clay slate to the sea floor. When the lava cooled down, different lava rocks such as diabase and quartz keratophyres were formed, depending on the chemical composition of the lava . During the Variscan Folding , around 100 million years later at the end of the Carboniferous Age, the former sea floor was raised to form high mountains . In the following millions of years this mountain range was eroded away again. During erosion, the harder lava rocks resisted weathering better than the clay slate surrounding them. So the rocks of the Bruchhauser stones remained, while the clay slate surrounding them disappeared.

Prehistoric finds

The Bruchhauser Steine Wallburg used to be located between the Bruchhauser Stones . Their fortification includes the four main rocks. These rocks were connected with ramparts, whereby today only parts of the ramparts are visible. During excavations , post holes from earlier wooden palisades were found in the walls.

The exact historical significance and use of the Bruchhauser stones is still unclear today. It is assumed to be used as a prehistoric refuge . It is also assumed to be used for cultic, economic, representative, administrative and political functions. It is unclear, for example, whether the Bruchhauser stones were permanently settled or rather served as a refuge. The archaeoastronomer Burkard Steinücken suspects that the Bruchhauser stones were used for calendar bearings of the moon and solstice dates.

On the basis of fragments found on and in the vicinity of the rocks, a meeting place for a rock sanctuary is assumed. A bronze, Iron Age hollow hump bracelet that was found in 2013 points in the same direction. Speculations that this is the famous Tamfana sanctuary mentioned by Tacitus cannot be proven based on the current finds.

The finds from the 8 hectare to at least 11 hectare complex date to the early and middle Iron Age (6th / 5th to 3rd century BC); It was visited again in the early and high Middle Ages. The oldest find was a small ax from the Neolithic Age .

In the years 1938, 1949 and 1996 to 1998 excavations were carried out in the area of ​​the earth walls on the Bruchhauser stones.

Flora and fauna

The rocks are of particular floristic importance for the whole of northwest Germany due to the Alpine rock cress ( Arabis alpina ) on the Bornstein and Ravenstein rocks , which are considered a relic from the Ice Age and are found here far beyond the main distribution. The next occurrences are only found in the Black Forest . Other special features are the hawkweed ( Hieracium onosmoides ) and the pale hawkweed ( Hieracium schmidtii ) on the field stone . The only occurrence of the folded lady's mantle ( Alchemilla plicata ) in North Rhine-Westphalia is in the meadows below the rocks . The moss and lichen flora also show some great rarities. Here, are particularly Blytts Craw Fork Teeth Moss ( Kiaeria blytti ) Spruces yellow bag Moss ( marsupella sprucei ) Douinis Moss ( Douinia ovata ) and Overlooked Krätzflechte ( Lepraria neglecta ) to name. Other very rare lichens such as the two bowl lichen Parmelia amphalodes and Parmelia incurva , as well as Schaeria tenebrosa and Lecidea caesioatra don't even have a German name. These mosses and lichens, which are very rare in Germany, are found primarily in the Alps and the Arctic.

The eagle owl ( Bubo bubo ) was found here until 1876 . The last brood in 1876, with three Junguhus, was robbed and taken to the zoo in Münster. Massive persecution resulted in the last brood for a long time in 1903 in the Hochsauerland in the city of Brilon. It was not until 1976 that the re-colonization of the Hochsauerland in the urban area of ​​Marsberg took place after bred eagle owls were released. In 1995 the rocks were also repopulated. Broods have been detected so far at Ravenstein , Bornstein and Goldstein .

Peregrine falcons ( Falco peregrinus ) have been shown to breed for the first time around 1900. But already Annette von Droste-Hülshoff , the most famous writer in Westphalia, wrote in 1840: "Hawks, falcons and owls settle in the jagged rocks and increase the impression of the wildly picturesque picture with their whistling and silent circling of the spikes." From 1967 to 1972 they were Bruchhauser Steine ​​is the only place still occupied in North Rhine-Westphalia. Then the rocks, like all of Germany north of the Neckar, were uninhabited. After the peregrine falcon had recovered due to massive protective measures, it was repopulated in 1989. The peregrine falcon has so far brooded on Bornstein and Ravenstein .

In the Bruchhauser Steine ​​conservation area there are also the species of rough-owl , black woodpecker and gray woodpecker . Earlier breeding birds are the common raven , jackdaw and kestrel .

Protected areas

The Bruchhauser Stones are officially designated as a ground monument and also as a nature reserve , fauna-flora-habitat and bird sanctuary - each with the name Bruchhauser Steine . The nature reserve Olsberg borders on these protected areas .

On March 24, 2017, the Bruchhauser stones were designated as the second national natural monument in Germany.

National geotope

On May 12, 2006, the Bruchhauser stones were awarded a National Geotope . On this occasion, the title National Geotope and the logo planeterde were awarded by the Federal Ministry of Education and Research . In addition, the geotopes have been immortalized in an accompanying book. The award was the result of a competition organized by the Hanover Academy of Geosciences (AGH). 77 significant geotopes in Germany and in the Sauerland, in addition to the Bruchhauser Stones, only the Rock Sea Hemer were awarded as a national geotope .

Sponsorship

Foundation President Hubertus Freiherr von Fürstenberg (2018) with the Order of Merit of the State of North Rhine-Westphalia

The area at the Bruchhauser Steinen was acquired by the State of North Rhine-Westphalia from the Fürstenberg family and looked after by their own foundation , the Bruchhauser Stones Foundation , established in 1992 . This publishes the rocks - viewed from a touristic point of view - in the context of flyers as a soil and cultural monument and on its website as a natural monument , although officially only soil monument applies.

Info center, admission and visitor numbers

The Bruchhauser Stones Information and Service Center (hereinafter referred to as the Info Center ) of the Bruchhauser Stones Foundation is located a little to the west below the Bruchhauser Stones at an altitude of almost 525  m . At the official entrance to the rocks located there, visitors have to pay an entrance fee and a parking fee for their vehicle. In 2015, the annual number of paying visitors was given as around 15,000; and around 1,000 visitors took part in a guided tour by a nature guide from the foundation.

Hiking and viewing opportunities

The Rothaarsteig leads past a few meters below the information center . For example starting at this house you can walk up to the rocks. You can explore the area of ​​the rocks via various paths with information signs , such as the forest and forest path , archaeological path , geological path and Gaugreben'scher Jägersteig . Since all paths connect to one another, they can also be walked as a circular route.

The rocks have been closed all year round as a climbing area since 1989 in order to protect the nature there. However, the Feldstein can be climbed on the Thomas-Neiss-Steige , which is partly secured with handrails and chains . From its summit there is a view down to Bruchhausen, the local Rothaargebirge, the Fredeburger Land in the southwest, the Arnsberg Forest in the northwest and the Teutoburg Forest in the north.

Launch pad for paragliders south of the Bruchhauser Steine ​​on the western slope of the Istenberg

Paragliding

About 300 and 630 m south-southeast of the Feldstein are two launch sites for paragliders : the southwest launch site with a kite ramp and the west launch site . There leads to the Info Center starting west past the rocks one at the coming of Bruchhausen access road (see section transport links followed) infrastructure ; it ends at the hikers' car park on the western highlands of the Istenberg.

Transport links

The district road  47, which runs from Assinghausen to and through Bruchhausen , leads to the west past the Bruchhauser stones, which leads to state road  743 ( Olsberg - Elleringhausen - Brilon-Wald / B 251 ) laid out north of the rocks . On the northern edge of Bruchhausen, a narrow spur road branches off from the K 47, which runs eastwards to the chargeable hikers' parking lot at the information center and thus towards the rocks. Alternatively, you can continue to follow the street from this parking lot (against payment) and drive to the aforementioned parking lot on Istenberg.
