Burghausen Castle is the longest castle complex in the world (1,043 m), confirmed by the Guiness World Record company. The castle hill was already settled in the Bronze Age. The castle (which was founded before 1025) was transferred to the Wittelsbachs after the death of the last count of Burghausen, Gebhard II, in 1168. In 1180 they were appointed dukes of Bavaria and the castle was extended under Duke Otto I of Wittelsbach.
With the first partition of Bavaria in 1255, Burghausen Castle became the second residence of the dukes of Lower Bavaria, the main residence being Landshut. In 1255 under Duke Henry XIII (1253–1290) the work for the main castle commenced. In 1331 Burghausen and its castle passed to Otto IV, Duke of Lower Bavaria.
Under the dukes of Bavaria-Landshut (1392-1503), the fortifications were extended around the entire castle hill. Starting with Margarete of Austria, the deported wife of the despotic Duke Henry XVI (1393–1450), the castle became the residence of the Duke's consorts and widows, and also a stronghold for the ducal treasures. In 1447 Louis VII, Duke of Bavaria died in the castle as Henry's prisoner. Under Duke Georg of Bavaria (1479–1503) the work was completed and Burghausen Castle became the strongest fortress of the region.
After the reunification of Bavaria in 1505 with the Landshut War of Succession the castle had military importance, and due to the threat of the Ottoman Empire it was subsequently modernised. During the Thirty Years War Gustav Horn was kept imprisoned in the castle from 1634 to 1641. After the Treaty of Teschen in 1779 Burghausen Castle became a border castle. During the Napoleonic Wars the castle suffered some destruction. The 'Liebenwein tower' was occupied by the painter Maximilian Liebenwein from 1899 until his death. He decorated the interior in the Art Nouveau style.
The gothic castle comprises the main castle with the inner courtyard and five outer courtyards. The outermost point of the main castle is the Palas with the ducal private rooms. Today it houses the castle museum, including late Gothic paintings of the Bavarian State Picture Collection. On the town side of the main castle next to the donjon are the gothic inner Chapel of St. Elizabeth (1255) and the knights' hall with its two vaulted halls. Opposite the Dürnitz are the wings of the Duchess' residence.
The first outer courtyard protected the main castle and also included the stables, the brewery and the bakery. The second courtyard houses the large Arsenal building (1420) and the gunsmith's tower. This yard is protected by the dominant Saint George's Gate (1494). The Grain Tower and the Grain Measure Tower were used for stabling and to store animal food; they belong to the third courtyard. The main sight of the fourth courtyard is the late Gothic outer Chapel of St. Hedwig (1479–1489). The court officials and craftsmen worked and lived in the fifth courtyard, which was once protected by a strong fortification. In 1800 this fortification was destroyed by the French under Michel Ney.
The Pulverturm ('Powder Tower', constructed before 1533) protected the castle in the western valley next to the Wöhrsee lake. A battlement connects this tower with the main castle.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.
