Jellhaugen is the second largest burial mound in Norway and among the largest in Scandinavia and Northern Europe. It has a diameter of 85 metres and a height of around 9 metres. It's difficult to know exactly how old it is, but another nearby burial site known as the Jellhaugen Mound has been dated to around 1,500 years ago.
A saga tells that the mound is buildt for a king called Jell, however these tales are from more modern times and cannot be trusted. The mound is not completely excavated, only parts of it have been excavated, in 1968 however, it was dug a ditch trough the centre of the mound and the only findings was a cremation grave with burned human bones and a single amber pearl. The grave has been carbon-dated to around 426-598AD, the end of the age of migration. Traces of a early grave robbing was dated to around 692-896AD.
In 2018, using high-resolution ground-penetrating radar, archaeologists have found an ancient Viking cemetery, complete with what appears to be a well-preserved ship burial. A popular mode of interment among the Norse Vikings, ship burials consisting of a longboat covered by a mound were reserved for important personages, such as chieftains.References:
Hochosterwitz Castle is considered to be one of Austria's most impressive medieval castles. The rock castle is one of the state's landmarks and a major tourist attraction.
The site was first mentioned in an 860 deed issued by King Louis the German of East Francia, donating several of his properties in the former Principality of Carantania to the Archdiocese of Salzburg. In the 11th century Archbishop Gebhard of Salzburg ceded the castle to the Dukes of Carinthia from the noble House of Sponheim in return for their support during the Investiture Controversy. The Sponheim dukes bestowed the fiefdom upon the family of Osterwitz, who held the hereditary office of the cup-bearer in 1209.
In the 15th century, the last Carinthian cup-bearer, Georg of Osterwitz was captured in a Turkish invasion and died in 1476 in prison without leaving descendants. So after four centuries, on 30 May 1478, the possession of the castle reverted to Emperor Frederick III of Habsburg.
Over the next 30 years, the castle was badly damaged by numerous Turkish campaigns. On 5 October 1509, Emperor Maximilian I handed the castle as a pledge to Matthäus Lang von Wellenburg, then Bishop of Gurk. Bishop Lang undertook a substantial renovation project for the damaged castle.
About 1541, German king Ferdinand I of Habsburg bestowed Hochosterwitz upon the Carinthian governor Christof Khevenhüller. In 1571, Baron George Khevenhüller acquired the citadel by purchase. He fortified to deal with the threat of Turkish invasions of the region, building an armory and 14 gates between 1570 and 1586. Such massive fortification is considered unique in citadel construction.
Since the 16th century, no major changes have been made to Hochosterwitz. It has also remained in the possession of the Khevenhüller family as requested by the original builder, George Khevenhüller. A marble plaque dating from 1576 in the castle yard documents this request.
A specific feature is the access way to the castle passing through a total of 14 gates, which are particularly prominent owing to the castle's situation in the landscape. Tourists are allowed to walk the 620-metre long pathway through the gates up to the castle; each gate has a diagram of the defense mechanism used to seal that particular gate. The castle rooms hold a collection of prehistoric artifacts, paintings, weapons, and armor, including one set of armor 2.4 metres tall, once worn by Burghauptmann Schenk.
