The Tropaeum Alpium ('Victory Monument of the Alps'), was built by the Romans for the emperor Augustus to celebrate his decisive victory over the ancient tribes who populated the Alps. The monument's remains are in the commune of La Turbie, a few kilometers from the Principality of Monaco.
The Trophy was built c. 6 BC in honor of the emperor Augustus to celebrate his definitive victory over the 45 ancient tribes who populated the Alps. The Alpine populations were defeated during the military campaign to subdue the Alps conducted by the Romans between 16 and 7 BC.
The monument as partially restored by archaeologists at the beginning of the 20th century, is 35 meters high. When built, according to the architect, the base measured 35 meters in length, the first platform 12 meters in height, and the rotunda of 24 columns with its statue of an enthroned Augustus is 49 metres high.References:
Ängsö Castle was first named as "Engsev" in a royal charter by king Canute I of Sweden (r. 1167-1196), in which he stated that he had inherited the property after his father Eric IX of Sweden. Until 1272, it was owned by the Riseberga Abbey, and then taken over by Gregers Birgersson.
From 1475 until 1710, it was owned by the Sparre family. The current castle was built as a fortress by riksråd Bengt Fadersson Sparre in the 1480s. In 1522, Ängsö Castle was taken after a siege by king Gustav Vasa, since its owner, Fadersson's son Knut Bengtsson, sided with Christian II of Denmark. However, in 1538 it was given by the king to Bengtsson's daughter Hillevi Knutsdotter, who was married to Arvid Trolle.
In 1710, the castle was taken over by Carl Piper and Christina Piper. Ängsö Castle was owned by the Piper family from 1710 until 1971, and is now owned by the Westmanna foundation. The castle building itself was made into a museum in 1959 and was made a listed building in 1965. It is currently opened to visitors during the summers.
The castle is a cubical building in four stores made by stone and bricks. The lower parts is preserved from the middle ages. It was redecorated and expanded in the 1630s. The 4th storey as well as the roof is from the expansion of Carl Hårleman from 1740-41. It gained its current appearance in the 1740s.
