Denghoog is a Neolithic passage grave dating from around 3000 BC on the northern edge of Wenningstedt-Braderup on the German Island of Sylt. The name Denghoog derives from the Söl'ring Deng (Thing) and Hoog (Hill).
Denghoog is an artificial hill created in the 4th millennium BC on top of a passage grave. The hill today has a height of around 3.5 metres and a diameter at the base of around 32 metres. The internal chamber is ellipsoid, measuring about 5 metres by 3 metres. Its roof is supported by twelve large boulders. The space between them is covered by dry stone walls made up of so-called Zwickelsteine. Three huge boulders, weighing around 20 metric tons each, form the roof of about 75 cm thickness. These stones are glacial erratics, carried here in the ice age from Scandinavia. The spaces between the roof stones are also filled with dry stone walling. A layer of firm blue clay, brought here from the eastern side of the island, mixed with stone fragments almost completely waterproofs the roof. Above this is a layer of yellow sand, covered by a final layer of humus.
A passage of six metres length and a height of one metre leads into the chamber. Several other stone blocks were found scattered around the base of the hill. These have been interpreted as the remains of a stone circle on top of the hill.
The hill was first opened for archeaeological research in 1868 by Ferdinand Wibel, a professor of geology. He found an undisturbed grave chamber that was divided in three sections.Wibel found a complete pottery jar and shards of 24 other vessels, 11 of which could be reassembled or completed. The largest of these, a Schultergefäss has a height of 38 cm and a diameter of 31 cm. Other burial objects included stone tools (hatchets, chisels, 20 flint blades, a pyrite bulb for making fire and two circular holed discs with a diameter of 10 to 12 cm. There were also six amber pearls (one of them labrys-shaped) and fragments of a seventh pearl. All of these findings are today exhibited at the Archäologisches Landesmuseum in Schloss Gottorf, in Schleswig.
By its shape and ornamentation, the pottery found inside the tomb indicates a date between 3200 and 3000 BC. It is likely that the Denghoog served as a burial site for a family or clan over a period spanning several generations.References:
The Château de Chaumont was founded in the 10th century by Odo I, Count of Blois. The purpose was to protect his lands from attacks from his feudal rivals, Fulk Nerra, Count of Anjou. On his behalf the Norman Gelduin received it, improved it and held it as his own. His great-niece Denise de Fougère, having married Sulpice d'Amboise, passed the château into the Amboise family for five centuries.
Pierre d'Amboise unsuccessfully rebelled against King Louis XI and his property was confiscated, and the castle was dismantled on royal order in 1465. It was later rebuilt by Charles I d'Amboise from 1465–1475 and then finished by his son, Charles II d'Amboise de Chaumont from 1498–1510, with help from his uncle, Cardinal Georges d'Amboise; some Renaissance features were to be seen in buildings that retained their overall medieval appearance. The château was acquired by Catherine de Medici in 1550. There she entertained numerous astrologers, among them Nostradamus. When her husband, Henry II, died in 1559 she forced his mistress, Diane de Poitiers, to exchange Château de Chaumont for Château de Chenonceau which Henry had given to de Poitiers. Diane de Poitiers only lived at Chaumont for a short while.
Later Chaumont has changed hands several times. Paul de Beauvilliers bought the château in 1699, modernized some of its interiors and decorated it with sufficient grandeur to house the duc d'Anjou on his way to become king of Spain in 1700. Monsieur Bertin demolished the north wing to open the house towards the river view in the modern fashion.
In 1750, Jacques-Donatien Le Ray purchased the castle as a country home where he established a glassmaking and pottery factory. He was considered the French "Father of the American Revolution" because he loved America. However, in 1789, the new French Revolutionary Government seized Le Ray's assets, including his beloved Château de Chaumont.
The castle has been classified as a Monument historique since 1840 by the French Ministry of Culture. The Château de Chaumont is currently a museum and every year hosts a Garden Festival from April to October where contemporary garden designers display their work in an English-style garden.
