The chapel gets its name from the particular mineral - the garnet - that in nature reminds a dodecahedron. The chapel is at the top of a mountain and it overlooks the Zillertal, the big valley beneath. The south facade overlooks a pool that collects the waters to be used during the winter for the artificial snow. The new building, in the shape of a rhombic dodecahedron set on a concrete base, has a wooden structure covered in sheets of corten steel on the outside. From the concrete base, a staircase leads to the interior space, where the visitor perceives the evenness of the geometrical space at a single glace. From the upper side of the prism filters the light that brings to life the even surfaces of the walls, clad in larch wood lath. The magic of this space is uninterrupted thanks to the light that comes streaming on the walls whose identical regular shapes produce different effects depending on the hours of the day.
