Going up the Via del Seminario you arrive in front of the Archbishopric.

Built by Count Giovanni Cobenzl in 1587, the palace, which the eighteenth-century historian Carlo Morelli defined as “the most beautiful house in our city at that time,” later passed to the noble Codelli family from Gorizia, who enlarged it and donated it to the treasury in 1749 so that it could become the seat of the Archbishop, who settled there in 1751.

Within the Palazzo Cobenzl complex, but accessible directly from Via Arcivescovado, is the Chapel of the Exaltation of the Cross, built in 1746 by order of Agostino Codelli, Baron of Fahnenfeld, as commemorated by the plaque on the floor. The building's distinctive feature is its oval floor plan and vaulted ceiling. Among the furnishings, the Rococo marble altar (attributed to Mazzoleni) stands out, along with the white marble tabernacle and the altar supported by two statues of angels. Of the historical and artistic heritage of the Archbishop's Curia, noteworthy are the 17th and 18th-century paintings, portraits of the Strassoldo family, and the extensive paper archive.
