The Tower of the Rooster, the Old Cathedral, Salamanca, Spain, 2007. This Romanesque cathedral was founded in the 12th century. The dome that covers its crossing springs from a double arcade that is daringly pierced with windows, a distant reflection of Hagia Sophia. The mass of four pinnacles at the outside corners counter the thrust of the dome's weight. The thrust of the vaulting is borne by four massive pinnacles. The vault of the apse was frescoed by the Early Renaissance painter Nicolas Florentino.
