A fifth-century basilica that was never rebuilt, and has been in the hands of one order for eight hundred years.

Chronology

422-432 — Peter of Illyria builds the basilica, on a site that may have been the home of a Roman woman named Sabina. Turismo Roma gives the foundation as 425. Structural impact: the three-aisled plan and the reused colonnade are set now and never replaced. What you see today: essentially this building.
c. 430-432 — the cypress doors are made, dating analysis placing them under Celestine I (421-431) or Sixtus III (431-440). Structural impact: the porch acquires the object the church is now most famous for. What you see today: eighteen surviving panels, including the first known publicly displayed crucifixion.
5th century — the dedication inscription in Latin hexameters is set above the doorway on the inside, gold letters on an azure ground. Structural impact: none. What you see today: the original mosaic frieze, in place.
1220 — Pope Honorius III invites Saint Dominic to take up residence at Santa Sabina. Turismo Roma dates the grant to 1219. Structural impact: a convent begins to grow beside the church. What you see today: the bell tower and the cloister, built for the new community.
5 June 1222 — the official Dominican foundation, by a transfer of property. Structural impact: the basilica becomes the order's Roman headquarters, which is why it was maintained rather than modernised. What you see today: a fifth-century interior that survived because its owners had no interest in replacing it.

Checked against Turismo Roma — Turismo Roma gives the foundation of the Basilica of Santa Sabina as 425 by Peter of Illyria, on an ancient site that may have been the home of a Roman noblewoman named Sabina, and describes it as an exceptionally well-preserved example of fifth-century Christian basilica architecture, Turismo Roma states that in 1219 Pope Honorius III granted the church of Santa Sabina to Saint Dominic of Guzman, founder of the Dominican Order, who established his residence there, leading to the construction of the bell tower and cloister (October 2026).
Checked against Wikipedia — Peter of Illyria built the Basilica of Santa Sabina between 422 and 432, a window that differs from the single year of 425 given by Turismo Roma, The cypress wood doors of Santa Sabina are generally agreed to be the original door from 430 to 432 and feature eighteen surviving wooden panels depicting biblical scenes, with dating analysis suggesting the door could date from the reigns of Celestine I, 421 to 431, or Sixtus III, 431 to 440, An original fifth-century dedication in Latin hexameters survives above the doorway inside Santa Sabina, and Pope Honorius III invited Saint Dominic to take up residence at the church in 1220, with the official Dominican foundation occurring on 5 June 1222 by a property transfer — dates that differ from the 1219 given by Turismo Roma (October 2026).
