The façade is adorned with seven oculi and is extremely sober. The symbolic number seven recalls several texts of the Bible, first and foremost the lamb with "seven horns and seven eyes" from the Apocalypse of John. Two of the seven oculi, walled up in 1858, were reopened in 2011.
The north side of the Cathedral, on Piazza del Duomo
The main entrance is not the one on the façade, but the portal built on the northern façade, which overlooks Piazza Duomo. This was built in 1376 by Zenone da Campione and was originally reserved for the entrance of lords.
Interior
The Pordenone - Conversion of Saul - Organ door.
The large organ, in the central nave
The interior consists of three naves. In the central nave, second span, there is the Renaissance organ relocated here in 1981 after the restoration work following the earthquake in Friuli. The original instrument, a 1515 work by Bernardino Vicentino from Venice, had been lost over the centuries and was restored by Francesco Zanin using period materials and methods. It is used for liturgy, concerts and numerous recordings. The chest, among the oldest in the world, is decorated with canvases and panels painted by Pordenone in 1525. The organ doors contain three depictions:
Assumption of Mary (closed doors);
Fall of Simon Magus (open door on the left);
Conversion of Saul (open door on the right).
In the parapet of the choir there are five panels with the Stories of the Virgin, while in the lateral spaces some Pages are depicted.
Presbytery
The presbytery is decorated with a cycle of fourteenth-century frescoes, clearly derived from the lesson that Vitale da Bologna had left in the cathedral of Udine. The unknown author is cited as the Master of the Pavilions and his works date back to the period 1350-1380.
The right wall is decorated with stories from the Old Testament:
Master of the Pavilions - Susanna bathing.
Creation of Adam and Eve
Expulsion from Paradise
Adam's Work
Killing of Abel
Lameus kills Cain
Noah's Ark
Sacrifice of Isaac
Jews in the desert
Capture of Jericho
David and Goliath

On the left wall, instead, there are stories from the life of Christ, derived from the New Testament:
Master of the Pavilions - Stories of Christ.
Nativity

Presentation at the Temple
Flight into Egypt
Massacre of the Innocents
Christ among the Doctors
Wedding at Cana

The back wall is dominated by the dramatic scene of the Crucifixion.

The chapel is dominated by the altarpiece Presentation at the Temple by Giovanni Martini (1503), with a frame between the vegetal intrigues the Mysteries of the Rosary and the Madonna of the Rosary with the Child Jesus and Saint Dominic, work of Gasparo Narvesa (1626-1627).
