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.

Lovely passage grave tucked away in idyllic Sylt surroundings - lake, ducks, lawns, church, wonderful thatched houses with beatiful flower gardens. Super chilled guy in ticket booth. Get away from 21st century stress, climb down into the cool interior of cyclopean masonary, muse on 5,000 years of history, and emerge cleansed through the narrow stone passageway. Best visited in morning, try to get place to yourself!

It's definitely worth visiting. And make time to talk to the very knowledgeable gentleman at the entrance booth. He is happy to share his extensive knowledge with you.

1000 Jahre älter als die Pyramiden und äter als Stonehenge! Sehr beeindruckend und sehenswert. Wir wurden von einem sehr sympathischen, kompetenten und humorvollen Mitarbeiter in die Sehenswürdigkeit eingeführt und waren sehr begeistert. Immer wieder gerne.

Very interesting. The employee is very friendly and takes a lot of time for his explanations - for 2.50 euros you learn a lot.

Doune Castle

Doune Castle was originally built in the thirteenth century, then probably damaged in the Scottish Wars of Independence, before being rebuilt in its present form in the late 14th century by Robert Stewart, Duke of Albany (c. 1340–1420), the son of King Robert II of Scots, and Regent of Scotland from 1388 until his death. Duke Robert"s stronghold has survived relatively unchanged and complete, and the whole castle was traditionally thought of as the result of a single period of construction at this time. The castle passed to the crown in 1425, when Albany"s son was executed, and was used as a royal hunting lodge and dower house.

In the later 16th century, Doune became the property of the Earls of Moray. The castle saw military action during the Wars of the Three Kingdoms and Glencairn"s rising in the mid-17th century, and during the Jacobite risings of the late 17th century and 18th century.
