English: Photograph of architect Ricardo Porro's school of modern dance, part of Cuba's National Art Schools. Porro conceived the modern dance school’s plan as a sheet of glass that had been violently smashed and fragmented into shifting shards, symbolic of the revolution's violent overthrow of the old order. The fragments gather around an entry plaza - the locus of the "impact" - and develop into an urban scheme of linear, though non-rectilinear, shifting streets and courtyards. The entry arches form a hinge around which the library and administrative bar rotate away from the rest of the school. The south side of the fragmented plaza is defined by rotating dance pavilions, paired around shared dressing rooms. The north edge, facing a sharp drop in terrain, is made by two linear bars, containing classrooms, that form an obtuse angle. At the culmination of the angular procession, farthest from the entry, where the plaza once again compresses is the celebrated form of the performance theater.
