adjoining the vestibule were once used as a chancellery and later also as living rooms; today the castle administration is housed here. The most remarkable room in the basement is the palace chapel. The chapel hall is the only room in the castle that extends over two of the long houses. It takes up a good quarter of the east and middle houses. In addition, the floor level of the chapel extends down to the basement, making it the only room that takes up more than one floor. The church was originally furnished in the Renaissance style and still contains a pulpit altar and a baptism from the middle of the 17th century, both works by Claus Gabriel. Under Duke Philipp Ernst, the chapel was furnished in a baroque style around 1717, and in 1847 it received a Marcussen organ . During restoration work in 1973, frescos from the time the castle was built were uncovered. To the west of the chapel is the house crypt in which the last burial took place in 1811 and in which 38 members of the ducal family are buried. In the castle chapel is a smoke barrel from the 13th century, the last known artifact from the destroyed monastery church. The chapel also served as the official parish church of the city of Glücksburg until 1965. It is still used today for church services, weddings and baptisms. In the western tower room of the basement, civil weddings can be carried out in consultation with the castle administration. First floor with the Red Hall The first floor is the actual living area; the ducal family's bedrooms and salons have been located here since it was built. The eastern rooms were originally assigned to the duke, the western rooms to his wife. However, this division was not maintained permanently. In the center of the floor is the richly furnished Red Hall (including paintings by Antoine Pesne). The room got its name from the red wallpaper it was once covered in. The 30 meter long, ten meter wide and four meter high hall extends over the entire floor area of ​​the central building. The ornamentation of the vault is one of the earliest stucco works in Schleswig-Holstein. The room served as a salon and living room as well as a ballroom of the castle. It also served as a hallway, as four rooms lead off from
