In the northern angle we can see the small tower of Alfonso X 'the wise', where the king studied the firmament, and the Tower of Juan II, 80 meters high, decorated with beautiful esgrafiados and twelve turrets. The visitor can climb to the top of the tower to enjoy the magnificent views of the city and the Pinarillo (wood that contains the Jewish cemetery), the church of Vera Cruz, the medieval neighbourhoods of San Marcos and Zamarramala, and the quarry from where most of the limestone used in building the Cathedral was taken.
Inside the monument and around the Patio de Armas - where periodically chamber music concerts are housed - and the Patio del Reloj, we can find the rooms. Particularly notable for their beauty, we must pay attention to the Ajimeces Room; the Galera Room – which coffered ceiling has been recently rebuilt – the Throne Room – with an outstanding mudejar ceiling; the Chimney Room; the Cord Room; the Pineapples Room; the Royal Chamber; the Queen's Dressing Room and the Chapel. Above everyone, the Kings Chamber stands out, containing an extraordinary coffered ceiling made of golden hexagons and rhomboids, and a curious frieze displaying 52 sitting images, polychromed, of the Kings and Queens of Asturias, Leon and Castilla from Don Pelayo to the Queen Juana I.
