Archbishop's Palace, Archbishop's residence in Siena, Italy.

The Archbishop's Palace is a three-story building next to Siena Cathedral with white and black marble stonework on its lower facade. It serves as the administrative headquarters and residence of the Archbishop of the Archdiocese of Siena-Colle di Val d'Elsa-Montalcino.

The old archbishop's palace, attached to the cathedral's right flank, was demolished in 1660 under the urban replanning promoted by the Sienese pope Alexander VII. From about 1665 a new palace rose on the site of the Casa dell'Operaio and the canons' houses, and between 1665 and 1670 the adjoining Loggia dei Canonici was also torn down. The first resident was Archbishop Alessandro Chigi Zondadari around 1715, and the brick upper facade was finished in 1718-1723.

The interior displays portraits of bishops and popes who shaped the religious life of the region over centuries. These paintings show how central the Church was to Siena's identity and power.

The building sits directly next to Siena Cathedral as part of the city's religious center. Visitors should know that it functions as an administrative residence and not all areas are open to the public.

The facade was rebuilt between the late 17th century and the early 18th century in a neo-Gothic style that copies 14th-century Sienese architecture, so the palace looks medieval although it is a Baroque-era construction. The windows of the piano nobile carry the crest of Archbishop Giovanni Pierallini, who restored the facade in 1877.
