On the first floor of the Archiepiscopal Palace there is the Hall of the Emblems, with emblems of the Archbishops hung on the walls; four large marble tombstones show the chronology. Several fine paitings, many of which date back to the XVIII century, decorate the interior.
The capacity is of 300 seats.
The Temple of Pomona is characterized, on the inside and outside, by fifteen Ionic columns, joined together by a Gothic pointed arch. The capitals, of Ionic style too, are made by four heads of the goddess Pomona and by a square plate crowning the capital made of concave faces.
Other findings of the temple include the paving, the attic with a central round arch, a trunk of the foundations, the single-lancet windows and a wall plaque
The temple is used as hall for exhibitions and fairs.
