The Hermannsdenkmal ('Hermann Monument') stands on the densely forested Grotenburg, a hill in the Teutoburg Forest range. The monument commemorates the Cherusci war chief Arminius (in German Hermann) and the Battle of the Teutoburg Forest in which the Germanic warriors under Arminius defeated three Roman legions under Varus in 9 AD. At the time it was built, the location of the statue was believed to have been very near the actual site of the battle, though it is now considered to be more likely that the battle actually took place near Kalkriese, a considerable distance to north west of the monument.
Earthworks of the monument began in July 1838, and the foundation stone was laid in October 1838. Problems emerged due the criticism for design and the financial viability of the project came to be questioned. It was inaugurated not before 1875, in the presence of Emperor William I and the crown prince, Frederick.
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.
