The Archiepiscopal Palace, in Piazza Patriarcato, is surely one of the most important and best known buildings of the city of Udine. It is situated near Piazza Primo Maggio, a few steps from the city centre. The original building dates back to the sixteenth century, when the Patriarchs of Aquileia decided to move from the Castle of Udine to another residence. In the eighteenth century the building was subjected to following modifications by Domenico Rossi, entrusted by Patriarch Dionisio Delfino. In fact, between 1708 and 1725, the wing with the library and the staircase were made, the central body was raised after the realization of the portal and the works in the north wing and the honour staircase were concluded. Since 1995 the Patriarchal Palace - now Archiepiscopal Palace - has been housing the Museo Diocesano e le Gallerie del Tiepolo (Diocesan Museum and Galleries of Tiepolo), which displays works of art collected from the churches of the Diocese and preserves many frescoes by the young Giambattista Tiepolo, which can be dated back to 1726-1729. The Archiepiscopal Palace, in fact, has become one of the most famous in the city mainly thanks to Tiepolo's masterpieces that adorn its rooms.
On the ceiling of the entrance staircase you can admire the wonderful fresco entitled "Fall of the rebel angels". The Galleria degli Ospiti (Gallery of Guests) features some of the most beautiful frescoes by the famous artist depicting themes from the Bible, while on the ceiling of the Red Room you can see the "Judgement of Solomon". The other rooms of the palace are precious as well, such as the Yellow Room with its elegant stuccos and the Blue Room with the grotesqueries by Giovanni da Udine. Noteworthy is the Delfino Library with its historical volumes, the incunabula and the paintings by Nicolò Bambini.
