Some materials from the monastery were reused as building material for the new castle. The former monastery grounds were flooded and dammed up into a large castle pond. Typical mansion in Schleswig-Holstein Occasionally French models are cited as the inspiration behind the castle - the floor plan of the castle is similar to the central building of Chambord - but it is a typical building of its era and region. The architecture is typical for Schleswig-Holstein from the Middle Ages and the Renaissance. "Sister buildings" can be found, for example, in the Nütschau Priory and above all in Ahrensburg Castle, which was built almost simultaneously. Glücksburg Castle is the largest and probably most well known structure of this form of Schleswig-Holstein architecture. The motto of the builder Johann III was G ott g ebe G lück m it F rieden (God Gives Luck With Peace). The letters G G G M F are therefore placed above the main entrance. The name of the castle is derived from this motto. Glück means luck, and Glücksburg thus means Luck Castle. The building was built in a stylistic transition period. While Johann's uncle Adolf I, for example, built more modern, three-winged buildings, with the Husum Castle or the Reinbek Castle, the nephew stuck to more traditional building forms of the region. And although it was planned and executed as a manorial residence, the location in the water, the embrasure like openings in the tower basements, the originally merlon towers and the high-lying first floor and the now-gone drawbridge of the courtyard still remind of a past in which a noble residence also had to be fortified. Execution The building stands on a 2.5-meter-high granite base and rises directly out of the water. The castle is made of white plastered brick, which was largely removed and reused from the demolished monastery. The base area is a square with an edge length of almost 30 meters, consisting of three individual houses, each with its own floor plan and roof. While the middle house accommodated the large halls and the vestibule, the two side houses were fitted with the living rooms. The palace chapel, with its east-facing altar wall, is the only room that was placed across the overall floor plan and is located in the east and middle house at the same time. In the four corners of Glücksburg Castle are four octagonal towers, each
