It was opened on July 1, 1960 by King Frederik IX and Queen Ingrid as the Royal Hotel.

The entire hotel – from the exterior façade through to the stainless-steel cutlery used in the restaurant and the Swan and Egg chairs gracing the lobby – was designed by the Danish architect Arne Jacobsen.

Since most of his work has been replaced by corporate standard fabrics and furniture, the hotel has been referred to as Jacobsens' Lost Gesamtkunstwerk.

He implemented this theme using green textiles and furniture combined with "organic shapes" and rigid geometric forms.

Some models were later adopted into mass production and have become design classics, which are exhibited in museums worldwide.

The building's sense of lightness emanates from its Lever House-inspired form with a two-story base supporting its lofty "punch card" tower.

The reinforced concrete frame structure erected in the tower has a curtain wall of aluminum profiles and transparent green and gray anodized glass.
