the gatehouse was primarily used as a stable building and coach house . Today it houses the museum shop and ticket office. The twelve-axis cavalier's house from 1685, facing west, was raised by one floor in the 18th century, and the curved gables of the attic were not added until 1856. As on the castle, the decorations were later removed again. Today the cavalier's house is used for private purposes and is inhabited. Garden Already during the time of the Rüdekloster, the monastery had a garden, which was lost after the grounds were laid down and the castle pond was dammed. With the exception of a kitchen garden from 1622, the palace was only given a larger park area in the 18th century. Under the gardener Jürgen Lorentzen, a small pleasure garden was laid out on the site of the later rose garden from 1706 to 1709. Since Glücksburg is surrounded by water on three sides and the outer bailey is in front of the fourth side, the larger park was placed behind the outer bailey from 1733 without direct reference to the castle. This baroque garden essentially consisted of a large parterre, which was aligned with an orangery building erected in 1743. in the 19th century, under the Duchess Anna Carolina, the formal decoration of the garden was abandoned, and the green areas were redesigned, inspired by English gardens . The baroque structure was largely retained, so that the framing avenues and the path system of the old garden have been preserved to this day. The orangery was renewed and received its present form in 1827. It is a classicist building with five axes, which is unusual for the region, with a small portico in the center. The orangery is now used for art exhibitions and concerts. The garden area is open all year round and accessible to visitors free of charge. Rose garden The Glücksburger Rosarium was set up in 1990 and 1991 right next to the palace garden, on the site of the former palace gardening facility. The former gardener's house forms the focal point. In the rosarium over 500 historical, English, climbing and wild roses are cultivated on an area of just under one hectare. The rosarium is no longer part of the public castle grounds and is privately managed, so access is chargeable. Castle pond The castle pond was artificially created in the 16th century
