A sumptuous throne room built between 1334-1354 whose ceiling represents the seven heavens of the Muslim cosmos. It is said that the Council that decided to surrender the city of Granada to the Catholic Monarchs took place inside this tower.
Antonio Fernández-Puertas has suggested that, the ceiling is the representation of the seven heavens of Islamic paradise, with the throne of God located in the eighth heaven, represented by the central area of mocarabes, the four trees of life are located in the diagonals. The dome is a wonderful piece of carpentry. It is composed of cedar wood covered with strapwork (laceria), with a large cube of mocharabes in the center, dotted with a multitude of stars, painted in such a way that they look like mother-of-pearl, silver and ivory.
Note about strapwork: In the history of art and design, strapwork is the use of stylised representations in ornament of ribbon-like forms. These may loosely imitate leather straps,parchment or metal cut into elaborate shapes, with piercings, and often interwoven in a geometric pattern. In early examples there may or may not be three-dimensionality, either actual in curling relief ends of the elements, or just represented in two dimensions. As the style continued, these curling elements became more prominent, often turning into scrollwork, where the ends curl into spirals or scrolls. By the Baroque scrollwork was a common element in ornament, often partly submerged by other rich ornament.
