You are standing in front of the bearing structure of the building! It consists of two concrete cylinders that run through the centre of the building and are inserted into each other. The outer one has a diameter of 13 metres, through which, for example, the doors to the hotel rooms pass.

But you can also see the same cylinder wall in the restaurant, where a major artwork made of glass and concrete, the Meteorite Fall, is suspended.

The inner concrete cylinder has a diameter of 5 metres and you walk along it as you go down the white staircase from the hotel rooms to the lobby. At that point, it's on your right hand. It runs from the basement to below the gallery on the tower and is therefore several floors higher than the outer tube.

The various floors of the building are suspended from these concrete columns on steel structures.
