The Deisterpforte is a 550 meter wide sloping valley pass at 130 m above sea level. NN up to 120 m above sea level NN between the Deister and the Kleiner Deister bei Springe in the Hanover region , Lower Saxony , Germany . The Haller river rises in the Deisterpforte . Several traffic routes and supply lines lead through the Deisterpforte.
etymology
Around the year 1000 the location of the karst springs in the Deisterpforte was mentioned in a border description of the Hildesheim diocese under the name Helereisprig . The Haller forms the border between the Diocese of Hildesheim in the south and the Diocese of Minden in the north. The location of the karst springs was called Hallerbrunn in 1631 , Haller Brunn in 1783 , Hallerbrunn in 1896 and Hallerbrunnen in 1950 . The town of Springe got its name from the Haller springs : it was called Hallerspring until the 18th century . Hans-Heinrich Seedorf suspects "that Haller means something like a noisy flowing brook ."
geography
The Deisterpforte is in the north of 355 m above sea level. NN high Ebersberg and in the south from 285 m above sea level. NN high Raher Berg limited. In addition to the supply lines, federal road 217 from Hanover to Hameln , a country road, two agricultural and forestry routes, the Hanover – Altenbeken railway line with the S-Bahn line 5 Paderborn - Hameln - Hanover Hbf - Hanover Airport and the upper reaches of the valley pass through the valley pass Haller River . On the forestry path on the edge of the Deister, the European long-distance hiking trail E1 leads through the Deisterpforte.
South of the Deisterpforte in the Hameltal are the towns of Bad Münder and Altenhagen I , the Dahle domain and the Sedemünder desert . The battle of Sedemünder took place there in front of the Deisterpforte on July 28, 1260 . To the north is the Hallertal with the town of Springe in the Springer Kessel . In this direction, 600 meters from the valley pass, there used to be a sawmill powered by the Haller; today there is a furniture factory there.
At the southern edge of the Deisterpforte there is a disused quarry on the slope of the Raher mountain. In the lower area of the quarry there is a club house, above the quarry rises up the mountain as a romantic valley. In addition, a forest path leads through the forest and cuts through the Bückethaler Landwehr , which is explained here on an information board. The forest path then leads to the town of Springe.
The Deisterpforte forest restaurant was built in 1876 by the Ratskellerwirt Christian Bauer on the outskirts of Springe as an excursion restaurant; it should reopen in 2019 after several years of renovation.
geology
The Deisterpforte is a 550 meter wide sloping valley pass at a height of 130 m above sea level. NN up to 120 m above sea level NN . It lies between the Deister with the 355 m high Ebersberg in the north and the Kleiner Deister with the 285 m high Raher Berg in the south. The mountain ranges of the Ebersberg and Raher Berg and the subsoil of the Deisterpforte consist of the roughly 160 million year old limestone of the Korallenoolith , which was formed during the Upper Jura .
The Deisterpforte served until 400,000 years ago as an input Gorge for the Weser River , the million and a half years of Hameln Coming crossed the Deisterpforte and by the current Hallertal around the Marienberg in the current northern Leinetal over flowed. The valley was shared from the Deisterpforte by the Haller and from the Rosenmühle by the Leine, which at the time flowed into the valley there.
The limestone of the Korallenooliths lies under the Deisterpforte up to a height of between 85 m above sea level. NN and 75 m above sea level NN . At these heights, the limestone of the corallenoolith was removed from the Weser over a period of more than 1.5 million years. This created a high and steep-walled entrance gorge between the Ebersberg and the Raher Berg, which 400,000 years ago was about 45 meters lower than the floor of today's Deisterpforte. In this gorge the Weser deposited its Weser gravel over the course of 1.5 million years . Later, the glaciers of the Elster Cold Age and the Saale Cold Age displace the Weser to the west and pushed through the Hallertal into the Deisterpforte. They unloaded the debris they had carried with them in the Hallertal and also filled the Deisterpforte gorge up to the current soil profile.
Ludger Feldmann writes:
“Based on the location of the old Weser deposits and other criteria, it can be proven that the river has flowed through the Deisterpforte for at least 2 million years. As the mightiest river between the Rhine and Elbe, it will probably have formed rapids and small cascades on the limestones in the Deisterpforte. After crossing this strait from west to east, it was able to spread out again and follow the general incline in wide meanders, first to the east and then from Nordstemmen to the north ... Immediately after leaving the mountain strait, it struck a wide meander arc to the north , which can be seen today in the up to 150 m high semicircular slope north of Springe formed by the heights of Ebers-Berg, Fahrenbrink and Bielstein. It is a typical form of erosion of a river, but the river has 'lost' it. "
archeology
Mammoth teeth were found in the gravel pits at Deisterpforte , which indicate that the valley pass served as a migration route for mammoth herds around 20,000 years ago.
In the Deisterpforte there was already a stick dam for the road from Hameln to Hanover in the Middle Ages . In the 14-15 In the 19th century, a thirty-meter-wide landwehr with three walls and four ditches was built to secure this traffic route . W. Netzel does not rule out a multiple period of the system and also considers a reference to the Angrivarian Wall possible. The Landwehr led on both sides of the Deisterpforte from the mountain slopes down into the valley, in which a three hundred meter wide swamp stretched next to the Knüppeldamm, which was crossed by the Haller and Wolfsthalbach. Well-preserved remnants of the rampart and ditch system are still preserved today in the parcels of Am Spielbrink and Über der Schanze .
On the Ebersberg as well as elsewhere in the Deister there are various groups of barrows . On the edge of the Deisterpforte there are four barrows in the Am Wolfstal parcel and five barrows in the Wolfstalskopf parcel .
Haller Quellen
The two karst springs of the Haller arise in the Deisterpforte . Above the Haller springs in the parcel Am Spielbrink was the Spielbrink court; the place of execution was in the Deisterpforte at the foot of the Ebersberg in the parcel Galgenkamp.
The two sources named Hallerbrunnen are on Raher Berg in the parcel Am Spielbrink at an altitude of 123.2 m above sea level. NN developed in a water extraction system of the water supply company Purena; Purena is a subsidiary of E.ON Avacon . The Hallerbrunnen pump spring water from the partially karstified coral oolite of the Upper Jurassic , which is supplemented by inflows from the 15 m thick Quaternary unconsolidated rocks. The catchment area of the springs and fountains extends about 3 km to the southeast into the Kleine Deister .
In the second half of the 18th century there was an artistically designed landscape and excursion garden called Lustgarten around the Haller spring, which the then bailiff F. Bussmann had laid out. A cut limestone with the inscription “SP. D. June 14, 1770. FB ”, which, according to Udo Mierau, shows a stylized tree and several depressions, which in a legend are interpreted as the devil's horse and human foot . The initials FB refer to the name of the official F. Bussmann. The writing is partly chipped and also badly weathered because the stone is exposed to the flowing water on the slope, the rain and the frost. On the other hand, the “stylized tree” can be interpreted as an arrow pointing towards the Haller spring. This hewn limestone is located near the Haller springs on the slope below the forest path that leads to the waterworks.
Other sources
Opposite on the slope of the Ebersberg there are also two springs in the parcels Großes Wolfstal and Kleines Wolfstal; from them rises the Wolfsthalbach, which unites with the Haller in the Deisterpforte. The Great Wolf Valley is a steep and deeply cut valley, which is 345 m above sea level. NN begins on the Fahrenbrink and cuts into the mountain with a steep bed and even steeper slopes. Barely 500 meters away from Fahrenbrink, it has already cut a hundred meters deep notch between Ebersberg and Wolfstalkopf. Over a length of 2100 meters, the Großer Wolfstal overcomes a height difference of 195 meters.
The coat of arms of the city of Springe
The Springer city coat of arms represents the three sources of Haller in the Deisterpforte. In each of the three corners of the coat of arms you can see a five-petalled rose: the shield and seal of the county of Hallermund, which existed from the 12th century .
