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:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
