The Regalia Room (room 24)
When you step into this small tower room, you step into the treasure chamber of absolute monarchy. Here, Christian V gathered the regalia as well as the majority of the crown's collection of precious items in gold and gemstones. The treasures were placed in two wall cabinets.

The Regalia Room – the treasure chamber of absolute monarchy
The Trouser Watering Chair
Unfortunately, none of the original decorations of the tower room have been preserved. The ceiling, created by the stucco artist C.L. Fossati, dates from a renovation in 1762.
Since the spring of 2025, the Regalia Room has housed a very special item – the Trouser Watering Chair, also known as Denmark's oldest whoopee cushion.
Behind the wallpaper door to the right lies the 'Green Cabinet'. It was a small, green-painted room in the tower extension, where the second finest items were displayed: handicrafts and miniature portraits.
Rosenborg Castle as a museum
When Rosenborg Castle was converted into a museum in the mid-1800s, the contents of the two cabinets were distributed among the various kings' rooms. However, the regalia were not exhibited to the public until 1922 in Christian V's Chamber.
In 1975, the current underground treasury was opened, where the regalia are now displayed along with the crown jewels. In 1994, the Green Cabinet in the basement was opened, where the beautiful handicrafts are now exhibited.
