The blind walls are outer walls that simply do not contain openings, so there are no windows or doors. These are often walls that are waiting for the construction of a terraced structure or that result from a poorly organized layout. They are often seen as a wound in the context of a coherent urbanization and are the object of more or less successful integration attempts such as the installation of frescoes or vertical gardens. Is it still necessary? Is there not an intrinsic beauty to these blind walls?
