Of almost triangular shape, there are head five streets. It overlooks on the left the Palazzo della Dogana, already seat of the Cinema Teatro Umberto, today made unfit for use by a fire, built in the Middle Ages for commercial purposes, remodeled in 1657 on the initiative of Francesco Marino Caracciolo, Prince of Avellino, designed by Cosimo Fanzago: it is a building of rough shapes, but not devoid of character, decorated with ancient statues, busts of Nero, Caligula, Commodus and the statue of Prince Marino I Caracciolo. In front of the palace stands the monument to Charles II of Hapsburg, vulgarly called "the king of abbrunzo", also by Fanzago.
