Oh, what dramatic words Charles-Edouard Jeanneret-Gris!
From here we gain a view of the interior of the “cloister" and the cell block’s interior with its many windows. Indeed, the structure is imposing with its brutal concrete seeming to the viewer like a bunker or massive bridge pier.
What makes this a good example of the use of concrete is that it uses concrete as a finish material. Nowhere in this structure is there a use of a finish material or coating for the concrete that is the structure. From the “pilotis” that support the building to the walls and even windows, concrete is used in its raw unfinished form.
Overall, the use of concrete in this building is not so amazing simply in its structural qualities. The “pilotis” system had been used many times by Le Corbusier. Rather, it was its combination of structure and aesthetics into a single unmasked entity: the building itself. The very austerity and starkness of the building was seen as beautiful and appropriate to its function as a place of self denial and meditation.
