Geology of the area
Between Sangerhausen and Wallhausen there is the lowland
of the river Helme. Most of the clays, silts, sands and gravel
are up to 2 million years old and more than 590 m in depth,
with which the Helme filled its lowland in the Pleistocene.
They form together with the rocks of the Tertiary the
unconsolitated sediment level. The 250 million years old clay,
silt and sandstones of the Triassic are deposited in the
subjacent table mountains (platform cover). Limestone,
anhydrite and salt rocks of the Zechstein belong to the
sediments of the platform cover, too.
Due to tectonic processes about 80 – 50 million years ago the
original flat deposits sediments changed their position.
Today rock formations of different aged rocks from different
sedimentation areas are laying beside and proving vertical
movements, stretching partly several hundred metres. These
tectonically caused fracturing is called “Saxonian fault block
tectonics”.
Soluble processes caused by water begin as soon as the rocks
of the Zechstein come near the surface due to their chemical
contents. The process is known as karstification. This
anhydrite karst can be found in the whole southern Harz
showing romantic caves, bizarre morphologic shapes and a
rare flora seen along the karst walking paths. The roughly
consolidated gravel (conglomerates) and the red sandstone
of the red beds are older than the chemical sediments of the
Zechstein. These are erosion results of the old Variscan
mountain building. They come to the surface in the area of
the Hornburg Sattel (anticline). The Basement with the rocks
of the Wippra Zone begins in the north. Caused by
metamorphosis (rock changing) during the formation of the
Variscan mountain building 350 – 330 million years ago
argillite and clay slates were formed out of clay and sandy
sea deposits of the Ordovician and Silurian. To the west,
sediments of the Lower Carboniferous follow.
Point Cone Mine Dump
Hohe Linde( 1 )
This mine dump can be seen far across the landscape thus
forming the name of landmark 12. The artificial hill north of
Sangerhausen is a visible monument of mining history,
especially copper mining closed down in 1990.
The basis for 1000 years of mining in the area of Sangerhausen
was a rock layer about 30 cm in size – the copper ore/copper
shale.
Mining in that area was first mentioned on 25 January 1006
in the deed of donation of the emperor Heinrich II (died in
1024).
Mainly gold and silver composed in a rare volume in the ore
beside other metals were mined. A copper mine was first
mentioned near Sangerhausen in 1388. The technological
development of mining can be seen impressively in the size
and composition of mine dumps and reaches from small
family mine dumps from the very beginning of mining to
huge point cone mine dumps from the recent past. In 1944 a
new mine was sunk in a depth of 52 m below surface north
of Sangerhausen. After the standstill during the war work
could be continued and in 1947 the sink work could start
again. Till 1953 the depth reached 686 m.
The first large copper mine in the mining area of Sangerhausen
received the name of Thomas Müntzer. Thomas Müntzer had
in his retinue not only farmers but also miners. Production in
the Thomas Müntzer mine came to a standstill in 1990.
About 20 million tons of deadrock are deposited in the Hohe
Linde forming a nearly 150 m high dump.
Wippra Zone Former quarry at the Pferdeköpfe ( 2 )
The Wippra zone stretches in
one line along north-eastern
direction from Breitungen via
the Kohlestraße (coal street)
to Gorenzen consisting of
metamorphic rocks. Driving
along the street from Grillenberg
to Wippra we cross the
Kohlestraße. Its name dates
back to the time then charcoal
was transported out of the
forest to the metallurgical
works.
Right at the crossing is a car park. Walking from there we
reach the former quarry in 5 minutes (N51°33.153’,
E 011°18.144’).
Greenschist can be found in the quarry. It was already
excavated before 1945. An Eisleben based company began
to quarry the rocks in 1951 again thus enlarging
the outcrop area by about 50 %. Different rocks
for street construction were won.
In 1960 the quarry was shut down. We pass a
geodetic point on our way to the quarry. That
is one out of five points set at different places
in the Harz in the 1960’s for watching the
potential Harz-raising effect.
Grillenburg ( 3 )
The ruins of the Grillenburg can be
found above the site Grillenberg
(N51°32.067’; E011°18.870’). We follow
the signs of the walking path starting
at a small parking place at the bottom
of the Schloßberge on the site. The
fortress was mainly erected using
conglomerates and sandstones of the
red beds – the rocks of the surrounding
area. Remarkable is the use of bricks
as construction material for the superstructure.
In 1217 the Grellenberch was first
mentioned in a document. Partly in -
habited in 1483, the fortress was a ruin
100 years later. The village is a lot older and is mentioned in the
so-called Hersfelder Zehntregister at the end of 9th cen tury. We
can find other witnesses of the past in the area of Grillen berg,
for example the deserted medieval village Wüstung Hohenrode.
Excavations have already been made there since 1930’s.
Mining museum Röhrigschacht
Wettelrode ( 4 )
The museum in Wettelrode is
embedded in the historic mining
landscape of the south-eastern
Harz foreland. Copper mining
history in the region – once the
largest copper ore mining area
in Europe – can clearly be seen
here.
The museum above surface
informs about the formation of
the deposit, geology and
mineralogy as well as mining.
The marking landmark can be seen far across the country – the
steel made winding apparatus. It is one of the oldest remaining
mine hoists of Europe. In the area of the mine dump an
exhibition about mine hoisting technology and machinery can
be visited, among it a rack railway only used in copper mining
below surface. A small exhibition informs visitors about the
Biosphere Reserve Karst Landscape South Harz. The mining
museum was opened in 1991. As miners would say we can go
down 283 m deep into the earth with an original winding
apparatus.
Then the mine train takes you 1000 m to a mining area of the
19th century. Exhibits from the very beginning till the modern
times show the development of the mining techniques and are
also explained and demonstrated there. The trip below surface
for up to 31 people takes 75 minutes.
Special guided tours can be booked
half a day or as a day trip in the
museum. The way to the museum is
easy to find. An interesting mining
trail begins at the mining museum
leading through the old mining area
of a length of 4 km. The two ways
witness copper mining from 14th to
19th century among it geologic
outcrops, water facilities, costeaning
ditches, mine dumps and a ventilation
oven. The mining trail passes the
lake Kunstteich built in 1728 and
used for mining purposes till 1880.
Here we can have a romantic rest in
the Waldcafe at the Kunstteich. If the
sun is shining the self-baked cake is
also served at the terrace. Guided tours can be booked on
request at the mining museum Wettelrode.Opening hours:
June – August Tuesday – Sunday 9.30 am – 5.00 pm
September – May Wednesday – Sunday 9.30 am – 5.00 pm

Rogenstein – Roestone Schlösschenkopf at Lengefeld ( 5 )
The Schlösschenkopf raises between
Sangerhausen and Lengefeld, crowned by the
Moltkewarte – a look out built in 1903 at its
highest point (N 51°29.573’, E011°16.245’).
Following the signs you can easily find the
walking path from Lengefeld to the
Moltkewarte.
Roestone was mainly used as construction
material. It was exploited from several small
quarries in the surrounding area of the
Moltkewarte. Near these sites we
can often see houses, churches
and walls built with Roestone.
This lime comes from the lower
bunter. About 240 million years
ago this area was covered by a
plane, warm, oversalted sea. Very
small sandy lime pearls (so-called
ooides) were formed in the moving
water looking like roe and
therefore called like that.
Karst Karst walking path South Harz
The karst walking path was built in 1982
and opens up the mountain range of the
anhydrite karst with its geologic features.
Some of the geologic points are set right
at the Karst walking path. Stretching along
200 km the walking path connects the
karst landscape of the south Harz across
the borders of the federal states Saxony
Anhalt, Thuringia and Lower Saxony. This
path follows mostly historic ways and is
marked in the Landmark 12 white – red – white. Showboards
give more information on karst features at certain points.
Numerous trails show witnesses of historic mining, mainly
copper mining, the bed of which (Flöz) goes from Pölsfeld in
the east to Ilfeld in the west. The villages along the karst
walking path have kept their typical unique feature and fit
harmonic into the surroundings. The village Hainrode was
even awarded with the silver medal in the federal competition
“Our village shall be nicer” in 2004.

Dinsterbachschwinde near
Questenberg ( 6 )
About one kilometre east of Questenberg not
far away from the road to Hainrode lays the
Dinsterbachschwinde as the biggest swallow
hole in the area of the karst walking path. It is
the place where the creek Dinsterbach continues
its way below the surface. At this place you will
find an information board. Wal king along the
grassland we reach the next board after five
minutes which informs about the swallow hole
right at its place. A further swallow hole, the
Ankenbergschwinde, is at the bottom of the
Ankenberg between Hainrode and
Großleinungen.
Bauerngraben ( 7 )
West of Questenberg we find the Bauerngraben,
a sink in the valley of the Glasebach,
which disappears at this place in a swallow
hole of a small river under a steep high karst
moun tain range. The sink itself fills from
time to time with water and then often
forms a lake – at other times it gets very dry
again. The car park at the road from Roßla
to Agnesdorf is a favourable start for a walk
to the Bauerngraben. You can follow the
signs and showboards explaining the
geological background.
In and around Questenberg Alabaster balls, glacial pans and
other witnesses of geology ( 8 )
other witnesses of geology ( 8 )
Embedded in the deep
break through valley of the
Nasse set in a unique
landscape we can find the
site Questenberg, marked
by the Queste.
The so-called Queste is a
sun symbol erected on top
of the Questenberg. The
saga says that the daughter
of the castle lord lost her
way when picking flowers
in the forest. Inhabitants of
the surrounding villages searched the child for the worried
parents. The child was finally found on the grassland near
Rotha at the third day of Pentecost sitting there with a crest,
which had two tassels. The castle lord gave an opulent
reward to the inhabitants. Since that day the green Queste
has been set up on the 3 day of Pentecost every year. The
so-called Questenfest takes some days and has been
celebrated since centuries. Gypsum with alabaster balls is
outcropping at the rock face at the eastern slope of the
Questenberg. Alabaster balls are formed out of calcium
sulfate, gathered at single places within the mother rocks
before hardening and then later indurated forming the
so-called alabaster balls. If you go on the road coming from
Hainrode you will have the best sight on it. The glacial pans
at the bottom of the Questenberg northern of the village are
also interesting. A showboard right at the place explains the
geology to visitors. Remarkable geology can also be found at
the breakthrough of the Nasse through the Wippra Zone,
about 1 kilometre above the Questenberg. Slates of the
Palaeozoic (Ordovician and Silurian) form impressive rock
faces. Starting your walk in Questenberg you can reach this
area in a 15 minutes walk.
Not far away from the village on the Schloss berg the ruin of
the Questen burg is dated
back to 13th century. It
was occupied by military
during the 30 year war
(1618 – 1648). Rocks of
the surrounding area
formed the con struction
material for it. Among
these you can find Zechstein
limestone, slates,
bunter and anhydrite.
The wooden Roland, a
symbol of the village,
and the neck iron at the
outer wall of the church
are symbols of lower
jurisdiction.
Heimkehle near Uftrungen ( 9 )
Today’s border between the federal
states Thuringia and Saxony-Anhalt is in
the area of the Alte Stolberg marked by
one of the largest karst caves in
Germany, the Heimkehle. The visitor’s
entrance of the Heimkehle is western to
the road between Rottleberode and
Berga in Saxony-Anhalt (N51°29.833’;
E010°57.283’). Visitors can see 750 m of the cave with a total
size of about 2 km. The way around leads to corridors and halls
among them the Große Dom, 22 m high. The Heimkehle was
first mentioned in a border document, dated back to 1735, first
attempts for opening up were made in 20th century. During
World War II a production plant of the Junkers Werke was
installed and the Heimkehle became an external camp of the
concentration camp Mittelbau-Dora (Landmark 7 ). Artificial
accesses were destroyed by blasting in 1946. Opening for
visitors was not before 1954. The large Heim kehle owes its
formation the meeting and rock solution force of the small
rivers Thyra with the Krebsbach and the Krummschlachtbach.Opening hours:
November – April Tuesday – Sunday 10.00 am – 4.00 pm

The Krebsbachwand near
Rottleberode ( 10 )
South west of Rottleberode the Alte
Stolberg peaks the Aue from the Thyra
and the Krebsbach with an area level
up to 100 m high. The Krebsbachwand
is a significant part of the soluble wall
of the Alte Stolberg marked by gypsum
quarrying. In that area of the wall the
gypsuming rate of the anhydrite was
higher than the solution rate of
gypsum, thus forming a 10 – 30 m
strong gypsum crust at the surface over the lower laying
anhydrite till the beginning of gypsum quarrying. This
gypsum crust was exploited between 1950 and 1990.
However, the precipice of the Krebsbachwand remained.
Re cultivation measures of the company Knauf bound the
Krebs bachwand into the sur rounding karst landscape aiming
to rebuild stable forests. However, a big part of poor rock
area, keeping visibly the geologic ground, forms a biotope for
rare species. Due to ongoing surface mining operations in
border areas of the Krebsbachwand the exposures are
unfortunately not accessible.
At the Geopoint visitors can find the most typical rock types
of the deposit. You can reach the Geopoint from the lake
Schlossteich in Rottleberode, driving through the Schlossstraße.
Passing the cemetery you will find the Geopoint
directly at the right roadside.
Neue Morungsburg ( 11 )
The ruins of the two fortresses Alt and Neu
Morungen are not far away from Morungen.
Alt Morungen was given up after erecting
Neu Morungen around 1200. We can find
bunter, Zechstein limestone and slates of the
sur roun ding area in the walls of the fortresses.
The region around Morungen can offer many
various geologic multiforms. Beside the Wippra
Zone stretching northern along the site
with its metamorphic rocks we can also see
conglomerates, catching the eye with a significant red. Close
to the Wippra Zone an ore veine goes along the area with
barite and yellow copper ore. We can easily see that ore veine
in an exposure below the Neue Morungs burg close to the
forest way in the valley northern the valley border
(N51°31.136’;E011°13.744’).
Open air museum
Königspfalz Tilleda ( 12 )
Königspfalz Tilleda ( 12 )
The Königspfalz set on the hill Pfingstberg
is close to the northern slope of the Kyffhäuser
mountains. Erected in 972 the Kyffhäuser
was a wedding present from
emperor OTTO II (955 – 983) for his
Byzantine wife THEOPHANO (about 955 –
991). Tilleda belonged to the most famous
palatinates of the empire till the late
medieval times. Fundaments and parts of the buildings were
exposed and partly reconstructed by substantial exca vations.
Today the whole facility forms a unique open air museum
showing an insight into people’s life in the medieval time. The
constructions are built from sandstone and dolomite, which
were quarried in the surrounding area. Millstone was broken
not far away from Tilleda in Thuringia. Witnesses can be seen
along the 4.5 km stretching walking way “Auf den Spuren der
Mühlsteine” (On the trails of millstones) starting at the
Streuobstzentrum in Tilleda.
Opening hours:
April to October 10.00 am – 6.00 pm
November & March 10.00 am – 4.00 pm

Reservoir Helme ( 13 )
At the end of Kelbra towards Sondershausen there is the
Helmestausee, over 600 hectares in size. Parts of the reservoir
(emptied in winter) is Ramsar wetland of international
importance and European bird protection area. More than
20,000 cranes regularly roost here in autumn. Beginning at the
parking place we follow our way towards west to the Numburg
through the riparial wood. Not far behind the Numburg, close
to the shore line a salt spring comes to the surface, eluviating
enbedded rocksalt and potassiferous salt layers of the Zechstein
and smelling like sulphur. Beside it you can find the ruins of a
small quarry with bunter.
Prehistoric mammoth skeleton Sangerhausen with Spengler
Museum ( 14 )
In the Spengler
Museum you can
adventure 6000
years of human
settlement in the
region of Sangerhausen.
About 2000
exhibits are shown
in six different
sections (geology,
nature study, palaeo
n tology, pre history,
town history,
mining). The biggest attraction is the complete skeleton of the
old mammoth. The first parts of the animal were discovered
in the ice-aged layers of the gravel pit near Edersleben in
September 1930. The local researcher ADOLF SPENGLER (1869 –
1961) saved the skeleton in the years 1932 and 1933.
Spengler’s home in the old town of Sangerhausen was opened
as an external museum in 2001. Walking from the museum
you can reach it by foot in about 15 minutes.
The museum’s administration offers guided tours and project
days as special programmes.
Sangerhausen is mentioned in a document from the 10th
century. Around 1249 Sangerhausen got the town right and
thus the permission to erect a town wall. The old town with its
widely renovated buildings is worth visiting. The church St.
Ulrici is dated back to the first half of the 12th century showing
a treasure of Roman esque architecture. The gothic church St.
Jacobi is also lovely to see with its rich interior design and
decoration. Sanger hausen’s
history has been connected
with the Saxonian dynasty of
the Wettiner since 1246. In
1815 Sanger hausen became
Prus sian and de- veloped to an
important indus trial area
within the second half of 19th
century. Town development
has been formed by copper
ore mining and metallurgy
since 14th century.
The remarkable Rosarium,
built in 1903, shows the most
famous rose collection of the world.
Opening hours of the Spengler Museum:
Tuesday to Sunday 1.00 pm – 5.00 pm
(Spengler’s home in the Hospitalstraße 56 only Sundays 1.00 pm – 5.00 pm).
