Marksburg as the only undamaged hilltop castle in the Middle Rhine Valley. In the early 12th century records mention the Noble Freemen of Brubach (who probably built the lower part of the keep around 1117), even though the castle itself is first referred to in 1231. The Lords of Eppstein built the Romanesque castle complex with its triangular layout, characteristic of the Staufer era. The Eppsteins were amongst the most powerful families at that time; four of them were archbishops and electors of Mainz, and one of them held the same position in Trier.
The castle was bought by Count Eberhard II of Katzenelnbogen (1283). These counts belonged to one of the wealthiest lineages in the Rhineland - one of the countesses of Katzenelnbogen was the mother of King Adolf of Nassau. The counts of Katzenelnbogen built the Gothic part of Marksburg Castle, giving it its striking form. When the last Count of Katzenelnbogen died in 1479, the castle passed to the Landgraves of Hesse, through the marriage of the heiress Anna to Heinrich of Hesse. Marksburg Castle was turned into a hill fortress with artillery batteries and ramparts (this work mainly carried by John 'the Belligerent').
When the old German empire broke up in 1803 the castle passed into the hands of the Duchy of Nassau. During this period our castle was only used as a home for disabled soldiers and as a state prison. As a result of the Austro-Prussian War of 1866 the castle was taken over by Prussia. Now it was used as apartments, but it was in danger of falling into decay because the administration did not seem to have done much against it.
In the year 1900, with the help of Kaiser WilheIm II, theGerman Castles Association was able to purchase the Marksburg for the symbolic price of 1,000 Gold Marks. This was done on the initiative of professor Bodo Ebhardt, privy court planner and architect in Berlin, who carried out extensive restoration of the castle.
Today this castle houses the headquarters and offices of the German Castles Association (DBV), whose main task is the protection and preservation of castles and stately homes. The association's impressive specialist library, comprising over 25,000 volumes plus records on castle history is now housed in the Philippsburg, also located in Braubach. The castle is open to the public around the year.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.
