House of Terror museum contains exhibitions related to the fascist and communist dictatorial regimes in 20th-century Hungary and is also a memorial to the victims of these regimes, including those detained, interrogated, tortured or killed in the building. The museum opened in 2002.
With regard to communism and fascism, the exhibition contains material on the nation's relationships to Nazi Germany and the Soviet Union. It also contains exhibits related to Hungarian organisations such as the fascist Arrow Cross Party and the communist ÁVH (which was similar to the Soviet Union KGB secret police). Part of the exhibition takes visitors to the basement, where they can see examples of the cells that the ÁVH used to break the will of their prisoners.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
