Opposite to this antesala is the Sala de las dos Hermanas (Vestíbulo of the two Sisters), so-called from two white marble slabs laid as part of the pavement. These slabs measure 500 by 220 cm (15 by 7½ ft). There is a fountain in the middle of this hall, http://manuelzflrt.izrablog.com/5792859/la-mejor-parte-de-la-puente
