 The frame of the rose window holds 52 carved heads, while the center of the rose window holds a carved head of the Christ.The newest part of the decoration are the three bronze doors which give access to the entrance of the cathedral.These were finished in 1970 by the Sicilian sculptor Emilio Greco (1913–1995) depicting mercies from the life of Christ and are surmounted by a sculpture of the Madonna and Child created by Andrea Pisano in 1347.
