Randers District and Lysnet Bakke, a hill more than 45 million years old.

A Taste of Denmark

During the winter season we usually drive a short tour closer to where we live. It's too cold to stay out for a long time like we do in summer. I'll often combine the tour with some church or manor photos, and this time we took the road north of Århus, first stop Spørring church. We were  lucky that day. The sun was shining after a dark week and the air was fresh. Good for the brain to get some sunlight they say -  and my brain felt better!

In the horizon were some low dark blue clouds looking like peninsulas in a sea. I don't know if you can see it?  And here were the silhouettes of trees upon a blue sky. Such lovely trees. There was no parking place by the church, so we had to park opposite by a little supermarket. Outside stood the most miserable Santa Claus I ever saw. He was so thin - his clothes were like put on a hanger, and his curly - and extremely shining - Santa-beard was placed upon his own beard, which was brown. He looked like the manager of the bank who had taken the role of Santa Claus. He was easily recognized, and I'm not sure the children were very impressed!

 



 

A nice church in Spørring with some good details. There was a strange stone in the church yard. Not like a usual hollow stone. I don't know if it was one of the ancient ones, those rock carvings from late Stone Age or from Bronze Age with carved or polished hollows. Since there are no written sources from that time, the experts have not agreed the meaning of these stones. They might be symbols of fertility, or used in sacrifice, or cult-tables in rituals etc. There are many ways to interprete these skålsten.
The sun was behaving well - look at sunshine on the church tower!  The church door was locked, like they usually are on a Saturday, but I can tell you who like unicorns that there is a frescoe with two unicorns at the tree of life inside the church! Outside are two chessboards on the wall - and those carved patterns are a mystery like the hollowed stones. No one knows how to make a certain interpretation of them. I believe they are the Devil's game board. When he played on this gameboard outside the church, he would not go into the church and disturb the service. But I might be wrong! No one knows. That's why it is so exciting to examine such things. Like a detective story.
chessboard, Spørring.

We went on and outside Spørring the landscape was covered in a light haze and the clouds began to gather. What now? You'll never know on a December afternoon. We came to Hadsten, just passing through. I have never been interested in the church in Hadsten which you can see on the photo I took from the car. I don't like the architecture, in my opinion it is boring. It's built in 1871-72. And the dull grey colour. No, I love the old Romanesque churches. Hadsten is a large village - almost a town - what we call a stationsby = railway town, between Århus and Randers. It has the shortest pedestrian zone in Denmark, 35 meter, with no name. In return Hadsten has got one of the largest model railways in Europe - called Model Railway Europe. But we must continue, for we did not stay in Hadsten. A few minutes later we heard screams and crying and I didn't know what it was. It was a tree with black flowers. Lots of rooks. What a racket. And close to a house! I'm glad I don't live there.
The next little stop was by the church in Lerbjerg, and here I couldn't find what was supposedly upon the wall, until I came home and looked in my book! Why didn't I look properly before we went out!

But it was lovely outside the church dike and later we took a little stop by a small water stream, Lilleåen ( the Little river). There is much water in the streams now. That's good. Fresh, cool water for the fish and the water plants.  Lilleåen is the most important inlet of the big river, Gudenåen, more than half of the sea trouts go up the Lilleå. It's a good fishing place.

There was some cattle grazing close to a farm. Maybe they had to go inside soon. It was cold. Well, I think they can go out all day and night if it's Hereford. There was a little fat calf. It looked so funny. It was almost shaped like a square.

Near the Lilleå was a fishing lake, but I don't think the lake has any inlet of the river. They put out trouts in the fishing lake for people to catch, so you're always certain to bring fish with you home for suppper. You don't have to go buy fish from the fishmonger. It's a nice place and people bring their lunch and the children are fishing together with their dad.





Then we came to Bidstrup where we have been  several times. There is a fantastic beautiful landscape around Bidstrup. The present building is from the 1600s. 

Although I've got a better photo of the building itself I thought you should see the newly cut trees. The red building is a corner of a farm building. The estate might have roots in a fortification from the Viking period. The name Bidstrup is from the 1300s and means the place of the bishop. 



A few minutes after Bidstrup we saw two dilapidated houses. I don't know if they belong to the Bidstrup estate, but if they do then it's not worthwhile to restore them! They are probably private - and I guess they 'll soon be broken down, leaving place for something new.  







                                                     
                                  





















And then uphill to a special place called Lysnet Bakke. Lysnet Bakke (hill) lies in a landscape which rises markedly from a plateau-landscape. The transition is especially marked by a long 30-50 m high  slope. The inside of the hill is clay, which in one word can be described as plastic clay. The Lysnet Bakke is now a clay pit, from where was earlier extracted the plastic clay. The clay pit gives opportunities to watch the many various clay types, which are from a period 45-55 million years ago. The red clay, which you can see in some places,  is what 's called the Røsnæs clay. It's found in a few places in Denmark. The clay was deposited in an ocean, which covered large parts of the present North Sea-area, like Holland, Beligum, North Germany and all Denmark. South of the highest point is a clay pit, where was earlier extracted clay for a production of clinkers. The pit is marked by slippage today. The calcareous underground with slippage in the plastic clay gives possibilities for a rich flora, and some listed orchids grow here.From the hill is a fine view down to the landscape with the river in the middle. Stone Age people lived down there after the ocean had disappeared and the hills were their hunting place.This hill we stand on has been here forever and ever.

Then we continued our day-tour from the hill, first along the gravel road, and then it went downhill  through a lovely landscape. A pretty red house lies in shelter in the middle of the hilly area.  



 



 
























                                                                                                      

Next little stop was Vissing church,  placed  halfway downhill. Some churches in this area are very marked by frost and weather. The granite ashlars have got cracks on the northern and western side of the building. I guess it's the weather, for it's rare to see such cracked stones in the old ashlar churches, although they have been here for a thousand years. suddenly saw a glimpse of a white cat on the church yard, but then it was just a little sculpture on a grave. There must be a sweet story about the cat's connection to this grave.
 

But the afternoon was icy cold. The wind had changed and I'm a sissy - sometimes. I wanted to go home to a warm house and have some good hot soup!

See you soon.

Lindenborg River Valley in Himmerland

Lindenborg Å (river)
Lindenborg river is a 47 km long river in East Himmerland. It has its source south of Rold skov, which is also  the source of the waters of Simested. Simested river runs south, while Lindenborg river runs north, where it passes Lindenborg manor and runs out into Limfjorden.



                                                                                                                                                                 


Blåkilde
Both rivers are good fishing places, but what is especially interesting about Lindenborg river are at least 16 spring-areas in a stretch of about 15 km along the river. Two of these springs are Lille Blåkilde and Blåhøl,  the water-richest springs in North Europe - they both give 150 liter pr.second. The reason for the many  springs is the chalk just below the surface. The rain water seeps down through cracks in the chalk, from where it gradually is being pressured from the chalk above. Upon weak spots like in river brinks is the water pressed out like a spring. Even in the hardest winter has the water a temperature all year of 7-9 degrees Celsius, the plants grow along the springs and the water is clean and drinkable.

Lindenborg river vally is a part of the designated Natura 2000 area nr. 18 (with Rold skov, Lindenborg river valley and Madum lake), and  Habitat-area dn bird-protection-area,  total 8.748 hectare. 

Lille Blåkilde is an impressive spring, it has three types of springs. They run together into a large brook, which gives 150 liter water pr second. By the help of radiotopic isotopes was measured that the water from the brink fell like rain about 50 years ago.

Everywhere in this large calcareous area in Himmerland is an important and interesting flora. The orchids love this calcareous soil, and there are many rare orchids like the rare lady-slipper in Rold forest - and on the cliffs and banks along the river is a flora worth a study for an avid botanist. There is also a rich bird-life, and  the clean, fresh water is a fine habitat for a rich, varied macro-invertebrate community. (An invertebrate that is large enough to be seen without the use of a microscope).

Yellow Bedstraw
Yellow bedstraw/ Gul Snerre ( Galium verum) is also named Virgin Mary's bedstraw. In the old days, before the Catholic church had changed the heathen plant names, it was called Freja's bedstraw. Before Christianity was it considered sacred and dedicated to Freja, who was the goddess of love, marriage and home. Therefore was the flowers put in the bed under women giving birth. After Virgin Mary took over the name, people believed that she had plucked the soft flowers for the baby Jesus to put in his crip.
But in daily life was the plant also put among the bedstraw in order get rid of fleas. The house wife hang it in the ceiling of the living room, partly as a decoration, since its yellow colour stays firm like an Eternelle, and partly for its spicy scent. When children had scabies they were given a bath with a decoct of yellow bedstraw. The plant was also used earlier for spicing beer. It contains an enzym, which makes milk run together. The Latin word verum means milk-running herb. The root was used for dyeing linen krap-red, and the flower tops to dye a yellow and olive green.

Hoary plantain
                                                                                                                                                                  The cyclist lady by the bridge told us that a cat had come down to her and her husband in the morning when they passed the brink by the river and placed a  dead mouse in front of her as a gift.

Spiked Speedwell
Spiked Speedwell/Aks Ærenpris (Veronica spicata) grows in Scandinavia and across Middle and South Europe to Asia Minor and East Asia. It grows in dry calcareous soil, often on cliffs, hills, pastures and often along the coast. In Denmark it grows here and there along the coast of Limfjorden and Kattegat and at the island of Bornholm, but it is rare in other parts of Denmark. It is a popular cultivated plant in the garden.

Parsnip
Parsnip/Pastinak (Pastinaca sativa) is  wild in Denmark,where it is common along roads and in meadows.  It is a very old cultural plant which earlier was used largely, but it was later supplanted by carrot and potato.
It has been cultivated for several thousand years in Central- and South Europe and was  an important part of everyday food. In Denmark was parsnip known since the Middle Ages, where it was used in medicine. The parshnip is somewhat similar to Hamburg parsley, but is larger and coarser. The parsnip, which grows wild, is not the same as the well-known parsnip roots we cultivate for food. The wild parsnip has a lesser root, but it is not edible. The parsnip contains a vegetable poison, named psoralen, the same as in Giant Hogweed, but it is not as strong in parsnip. The sap can in combination with sunlight give blisters and wounds of the skin, which remind about burns.

Wild Mignonette
Wild Mignonette/Gul Reseda (Reseda lutea) is a species of fragrant herbaceous plant. Its roots have been used to make a yellow dye called "weld" since the first millenium BC, although the related plant Reseda luteola was more widely used for that purpose. The wild Mignonette grows in dry calcareous soil and is much visited by bees. It is rare to see other insects than honeybees in wild Mignonette, which is rare in other plants.


Sct. John's Wort


Sct. John's Wort/Prikbladet Perikon  (Hypericum perforatum) grows wild everywhere in Denmark. It grows in a dry and poor soil, where it is doing well among grass and other plants. The plant contains substances, which have inhibitory effects on depression. It is valuable a valuable bee-plant. The blooming buds are fine for a pretty and well-tasting snaps. The plant is used in herbal medicine as an adjunct or replacement for Prozac. Use of Sct. John's Wort can make the skin sensitive to sunlight.

The use of  Hypericum is not a proven treatment for depression. If the depression is not treated correctly and enough, then the state of the disease might worsen. Combined with certain  antidepressants hypericum can worsen side-effects like nausea, anxiety, headache and confusion.

The name Sct. John's Wort origins from the Middle Ages, where the tradition was to burn the flowers of the herb on Midnight's Eve (Sct. Johns day = 24 June). The superstition said that itiwas possible to drive away evil demons ( insanity) from the family, if they burnt the flowers of Sct. John's Wort. Later was it known that brandy with Hypericum was good for depressed persons.


Small Burnet
Small Burnet/Salad Burnet/ Blodstillende Bibernelle (Sanguisorba minor) . The Latin sanguis means blood and sorbeo means absorb, referring to the wound-healing and blood-purifying properties of the plant. It was used to heal many diseases in the old days, like the dried root was used against cancer. The Small burnet grows in dry, grassy soil, often on limestone soil. The leaves have a fine taste like cucumber and can be used in salads, soups, drinks etc.  The young leaves are considered interchangeable to mint leaves in drinks. The plant has a respectable shistory, it was called a favorite herb by Francis Bacon and was brought to the New World with the first English colonists.
