The grid floor runs along the natural stone wall and opens up the area in front of the openings, supplemented by a railing at the passageway.
Gratings were installed in the solid grating version made of Corten steel, used as a walkable walking and recreational surface. The design is implemented with a mesh size of 33 x 22 mm and emphasizes the restrained, robust effect in a rust look. The result is a functional path surface that blends in with the historical surroundings.
