The front elevation of the Cathedral is distinguished by the sense of grandeur of its portico. From its very foundation, it was intended to take the faithful by the hand on a journey, steeped in mysticism and wonder, into the imposing building of Monreale, dedicated to Santa Maria la Nuova. As early as the external square, you are invited to enter the Temple through the Gate of Paradise, built by Bonanno Pisano, whose ogival arch stands at the centre of the façade between the two towers. The monumental bronze door, commissioned by William II of Altavilla, consists of a wall of relief images, closed by architectural frames decorated with motifs that differ in form and materials used.
