Kernavė was a medieval capital of the Grand Duchy of Lithuania and today is a tourist attraction and an archeological site. In 2004 Kernavė Archaeological Site was included into UNESCO world heritage list. The area of Kernavė was sparingly inhabited at the end of the Paleolithic era, with the number of settlements significantly increasing in the Mesolithic and Neolithic eras. It is believed, that first inhabitants settled in Kernavė territory in 9-8 millennium BC, but only in the first centuries AD they started to form bigger settlements in the Pajauta valley (Kernavė territory). Settlements were protected by five fortified mounds, which still remain.
The town was first mentioned in 1279, when, as the capital of the Grand Duke Traidenis, it was besieged by the Teutonic Knights. In 1390, during the Lithuanian Civil War (1389–1392), the knights burned the town and its buildings in the Pajauta valley, including the castle. After this raid, the town wasn't rebuilt, and the remaining residents moved to the top of the hill instead of staying in the valley.
In later years, the remains of city were covered with an alluvial earth layer, that formed wet peat. It preserved most of the relics intact, and it is a treasure trove for archaeologists, leading some to call Kernavė the 'Troy of Lithuania'. For example, Kernavė has the oldest known medgrinda, a secret underwater road paved with wood. The road was used for defense and dates from the 4–7th centuries.
The site became the subject of wider interest again in the middle of 19th century, when a romantic writer, Feliks Bernatowicz, depicted the area in his novel Pojata, córka Lizdejki in 1826. The hillforts were soon excavated by the Tyszkiewicz brothers and then by Władysław Syrokomla (1859). After World War II, the excavation works were restarted by Vilnius University in 1979, and then again by the Lithuanian Institute of History between 1980–1983.References:
Varberg Fortress was built in 1287-1300 by count Jacob Nielsen as protection against his Danish king, who had declared him an outlaw after the murder of King Eric V of Denmark. Jacob had close connections with king Eric II of Norway and as a result got substantial Norwegian assistance with the construction. The fortress, as well as half the county, became Norwegian in 1305.
King Eric's grand daughter, Ingeborg Håkansdotter, inherited the area from her father, King Haakon V of Norway. She and her husband, Eric, Duke of Södermanland, established a semi-independent state out of their Norwegian, Swedish and Danish counties until the death of Erik. They spent considerable time at the fortress. Their son, King Magnus IV of Sweden (Magnus VII of Norway), spent much time at the fortress as well.
The fortress was augmented during the late 16th and early 17th century on order by King Christian IV of Denmark. However, after the Treaty of Brömsebro in 1645 the fortress became Swedish. It was used as a military installation until 1830 and as a prison from the end of the 17th Century until 1931.
It is currently used as a museum and bed and breakfast as well as private accommodation. The moat of the fortress is said to be inhabited by a small lake monster. In August 2006, a couple of witnesses claimed to have seen the monster emerge from the dark water and devour a duck. The creature is described as brown, hairless and with a 40 cm long tail.
