ThePalazzo San Callisto (also known as thePalace of Saint Callixtus) is a Baroque palace in theTrastevere neighborhood of Rome and one of the extraterritorialProperties of the Holy See.[1] The original Palazzo is located in thePiazza di Santa Maria in Trastevere, the later extensions have their entrance inPiazza di San Callisto. The entire complex is one of the areas of the Holy See regulated by the 1929Lateran Treaty signed with the Kingdom of Italy. As such it hasextraterritorial status.
In the courtyard of the palace is the well where, according to tradition,Pope Callixtus I was martyred in the year 222.[2]
The palace was originally the residence of the titular cardinals of the Basilica ofSanta Maria in Trastevere and was renovated in the 16th century under CardinalGiovanni Morone by architectOrazio Torriani.Pope Paul V granted the palace to the monks of the Order of St. Benedict who had to leave their previous monastery due to an extension of theQuirinal Palace. The building took the name of the small adjacentchurch of San Callisto. Between 1610 and 1618 both the church and the convent were renovated.[3]
In 1936 during the pontificate ofPope Pius XI the architectGiuseppe Momo, known for the double helix staircase of the Vatican Museums, designed the construction of a new wing.[2]
One facade of the palace faces the celebratedFountain in Piazza Santa Maria in Trastevere.
