The basilica was constructed in the fourth century and is recorded as theTitulus Crescentianae, thus relating the church to a certain Crescentia (possibly a Roman woman who founded the church.) According to tradition, the church was established byPope Anastasius I (399–401).
San Sisto was rebuilt in the early 13th century byPope Innocent III. The current church is the result of the restorations ofPope Benedict XIII in the 18th century, which left only thebell tower and theapse from the medieval church.
A 13th-century fresco cycle depicting scenes from the New Testament and the Apocrypha has been preserved.

Pope Honorius III entrusted the reform of the monastery at San Sisto Vecchio toDominic in the 1220s, intending it as part of the reformation of women's religious life in Rome. In 1219 Honorius then invited Dominic and his companions to take up permanent residence at the ancient Roman basilica ofSanta Sabina, which they did in the early 1220. After that they founded a convent andstudium on June 5, 1222, thus forming the originalstudium of theDominican Order in Rome, out of which the 16th-century College of Saint Thomas atSanta Maria sopra Minerva and thePontifical University of Saint Thomas Aquinas (Angelicum) would grow.[relevant?][1]
Dominican nuns still occupy the monastery at San Sisto Vecchio.[2]

III, note 50: "If the installation at Santa Sabina does not date from 1220, at least it is from 1221. The official grant was made only in June, 1222 (Bullarium O.P., I, 15). But the terms of thepapal bull show that there had been a concession earlier. Before that concession, the Pope said, the friars had nohospitium in Rome. At that time St. Sixtus was no longer theirs; Conrad of Metz could not have alluded to St. Sixtus, therefore, when he said in 1221: "the Pope has conferred on them a house in Rome" (Laurent no. 136[full citation needed]). It is possible that the Pope was waiting for the completion of the building that he was having done at Santa Sabina, before giving the title to the property, on June 5, 1222, to the new Master of the Order, elected not many days before.""Work III: Years of Experimental Activity (1215-19)".
