The primeval world museum on the castle area of Kusel presents itself, on the basis of the exhibit, as a careful intervention of human into nature.

Like a preservation of fossil, the architecture from available rock formation seems to arise, and bump by the surface in area of the hillside.

In connection with wall discs the inner space gets protected and form is given to the building.

The main part of the exhibition space rests subterraneously. Where the building is above ground, one recognises the horizotal stratification of  local rocks.

Daylight appears through a layered arrangement

of glass and let the building provide the right atmosphere for fossils.
