Lejre was the capital of an Iron Age kingdom sometimes referred to as the Lejre Kingdom. According to early legends, this was ruled by kings of the Skjöldung dynasty, predecessors of the kings of medieval Denmark. Legends of the kings of Lejre are known from a number of medieval sources, including the twelfth-century Gesta Danorum written by Saxo Grammaticus and the anonymous twelfth-century Chronicon Lethrense, or Chronicle of Lejre. As the home of the Skjölding dynasty mentioned in Beowulf, Lejre has long been thought to have been the real-world counterpart to Heorot, the fabulous royal hall where the first part of the action of that Anglo-Saxon poem takes place. Among other works of the medieval imagination that tell of adventures at Lejre, the best known is the fourteenth-century Icelandic Saga of King Hrolf Kraki.
Archeological excavations undertaken since the 1980s have produced dramatic confirmation that medieval legends of Lejre, though largely fabulous, have a basis in history. Research teams have uncovered the remains of an extensive Iron Age and Viking Age settlement complex just outside the hamlet of Gammel Lejre. Discovered here were the post-holes for a series of large rectangular buildings measuring fifty to sixty meters in length or more. These must have been the halls of powerful magnates or kings. Outbuildings and other structures whose remains were unearthed in this same area indicate that Lejre was also a center for crafts, commerce, and religious observances. The relative absence of weapon finds suggests that the site was more important as a social and economic center than as a military base. A noteworthy loose find that has recently turned up is a tiny silver Viking Age figurine known as Odin from Lejre. This is thought to depict the god Odin enthroned in majesty between ravens.
Other sites of archaeological interest in the vicinity, long admired by visitors even when their nature was not well understood, are a Viking-Age cemetery that includes several ship settings, a great Iron Age cremation mound, a number of tumuli that are mostly of Bronze Age date, and several Neolithic chamber graves, including one that in modern times has been known as Harald Hildetandshøy. As for the Iron Age archaeological settlement complex unearthed since the 1980s, its two related parts span the period from about 550 to about 1000 AD, thus confirming the significance of this 'land of legends' over a period of almost half a millennium, up to the time when Denmark was converted to Christianity and a new royal capital was established at what is now the cathedral city of Roskilde.
Czocha Castle is located on the Lake Leśnia, what is now the Polish part of Upper Lusatia. Czocha castle was built on gneiss rock, and its oldest part is the keep, to which housing structures were later added.
Czocha Castle began as a stronghold, on the Czech-Lusatian border. Its construction was ordered by Wenceslaus I of Bohemia, in the middle of the 13th century (1241–1247). In 1253 castle was handed over to Konrad von Wallhausen, Bishop of Meissen. In 1319 the complex became part of the dukedom of Henry I of Jawor, and after his death, it was taken over by another Silesian prince, Bolko II the Small, and his wife Agnieszka. Origin of the stone castle dates back to 1329.
In the mid-14th century, Czocha Castle was annexed by Charles IV, Holy Roman Emperor and King of Bohemia. Then, between 1389 and 1453, it belonged to the noble families of von Dohn and von Kluks. Reinforced, the complex was besieged by the Hussites in the early 15th century, who captured it in 1427, and remained in the castle for unknown time (see Hussite Wars). In 1453, the castle was purchased by the family of von Nostitz, who owned it for 250 years, making several changes through remodelling projects in 1525 and 1611. Czocha's walls were strengthened and reinforced, which thwarted a Swedish siege of the complex during the Thirty Years War. In 1703, the castle was purchased by Jan Hartwig von Uechtritz, influential courtier of Augustus II the Strong. On August 17, 1793, the whole complex burned in a fire.
In 1909, Czocha was bought by a cigar manufacturer from Dresden, Ernst Gutschow, who ordered major remodelling, carried out by Berlin architect Bodo Ebhardt, based on a 1703 painting of the castle. Gutschow, who was close to the Russian Imperial Court and hosted several White emigres in Czocha, lived in the castle until March 1945. Upon leaving, he packed up the most valuable possessions and moved them out.
After World War II, the castle was ransacked several times, both by soldiers of the Red Army, and Polish thieves, who came to the so-called Recovered Territories from central and eastern part of the country. Pieces of furniture and other goods were stolen, and in the late 1940s and early 1950s, the castle was home to refugees from Greece. In 1952, Czocha was taken over by the Polish Army. Used as a military vacation resort, it was erased from official maps. The castle has been open to the public since September 1996 as a hotel and conference centre. The complex was featured in several movies and television series. Recently, the castle has been used as the setting of the College of Wizardry, a live action role-playing game (LARP) that takes place in their own universe and can be compared to Harry Potter.
