The earliest data regarding human settlement at Vallimäe in Rakvere come from the Viking Age, an arrowhead from the 9th century and some broken pieces of pottery from this period have been found on the territory of the castle. There is more information about the last centuries of the prehistoric age when an ancient wooden stronghold surrounded by a fence stood in the place of the present convent building.
First written records about the stronghold called Tarvanpea come from the year 1226. In the middle of the 13th century the Danes started to replace the wooden stronghold with a more modern stone fortress.
After Virumaa and Harjumaa passed into the possession of the Livonian Order in 1347, a grand-scale reconstruction of the castle was carried out in several stages. In the first half of the 16th century a convent-type castle with a rectangular main tower was completed, it had strong flanks, a large front yard and an eastern gate consisting of several parts: the outer gate included a pitfall and a drawbridge and the inner gate had a lowered lattice. Living quarters and outbuildings were located in the front yard, near the circular wall.
During the Livonian war (1558–1583) the castle was attacked and damaged by the Russians, but it ended up under Swedish control. From 1602 to 1605 Rakvere fortress fell under the control of the Polish-Lithuanian commonwealth. When they retreated from Rakvere in 1605 during the war with Sweden, they blew up the castle.
Today Rakvere castle is open to the public. In addition to the museum you can taste knights’ favourite drink, a Malvasia wine, made after the oldest recipe at the wine cellar.
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.
