The Regalia Room (room 24)
When you enter this small turret room, you are standing in the treasury of the absolute monarchy. This is where Christian V kept the regalia and most of the gold and jewels belonging to the Crown. The treasures were kept in two cabinets that were carved into the walls.

The Regalia Room – the treasuryr of absolute monarchy
The wetting trap chair
Unfortunately, none of the original decoration of the turret room has been preserved. The ceiling, which was made by the stucco worker C.L. Fossati, dates from a renovation that took place in 1762.
Since spring 2025, the Regalia Room has housed one very unusual item: the ‘wetting trap chair’, also known as Denmark’s oldest whoopee cushion.
Behind the jib door lies the Green Room, a small green-painted room in the turret extension, where the second finest items were displayed: artisanal craft objects and miniature portraits.
Rosenborg Castle as a museum
When Rosenborg Castle was turned into a museum in the mid-19th century, the contents of the two rooms were distributed into the rooms of the related kings. However, the Regalia were not displayed to the public, in Christian V’s Room, in 1922.
In 1975, the present underground treasury was opened where the regalia are now on display along with the crown jewels. In 1994, the Green Room opened in the basement as a showcase for beautiful artisanal craft objects.
