Glücksburg Castle is one of the most important Renaissance castles in northern Europe. It is the seat of the House of Schleswig-Holstein-Sonderburg-Glücksburg and was also used by the Danish kings. Situated on the Flensburg Fjord the castle is now a museum owned by a foundation, and is no longer inhabited by the ducal family.
The castle was built from 1582 to 1587 by Nikolaus Karie for John II, Duke of Schleswig-Holstein-Sonderburg, (1545-1622) at the site of an former monastery, the building material was partly reused in the castle. The grounds of the monastery were then flooded to create a large pond almost entirely surrounding the castle.
The castle is built on a 2.5 metres high granite foundation that emerges from the water. The bricks used for the construction were mainly taken from the demolished monastery. The base area is a square with sides of nearly 30 metres, consisting of three separate houses with their own roofs. While the great halls and the vestibule are situated in the middle house, the living space is in the two side houses. The chapel is the only room that is part of two houses.
The building had typical renaissance adornments, that were removed in the 19th century, otherwise the exterior has remained more or less unchanged for over 400 years.
The kitchen garden created in 1622 was the castles only garden until the eighteenth century, as the old monastery garden was lost with the construction of the pond, that was built as defence structure, but also used for fishing. Between 1706 and 1709 a small pleasure garden was created in the area of today's rose garden. From 1733 on, a baroque garden was laid out in the main park in front of the outer buildings, where an orangery was constructed in 1743.
In the twentieth century, the formal gardens were remodelled into English landscape parks, though the sections of the older garden remain. The orangery was renovated in 1827 into a neoclassic building, and is now used for art expositions and concerts.
The Glücksburger Rosarium was created in the area of the former castle nursery in 1990/91, and grows more than 500 different roses. In contrast to the castle gardens, it is a private garden and has an admission fee.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.
