A medieval masterpiece often overlooked

The Basilica of San Lorenzo fuori le Mura is a treasure chest of medieval art, far from the crowds of the center. Its unusual layout, born from the merger of two basilicas, makes for a visit full of surprises. Here is what not to miss.

The tomb of St Lawrence

The heart of the basilica is the tomb of St Lawrence, the martyr deacon, kept beneath the high altar in the confessio. It is the very reason the basilica exists and has drawn pilgrims for centuries. Beside it are venerated the memories of other saints tied to the place. We explore the martyr's story in the article St Lawrence the martyr and the gridiron.

The Cosmatesque floor and the ambones

The interior preserves splendid medieval features:

  • The Cosmatesque floor, with its refined polychrome marble inlays.
  • The two medieval ambones (pulpits) and the twisted Paschal candlestick.
  • The inlaid episcopal throne (cathedra).
  • The ancient reused Roman columns.

These are precious witnesses to the art of the Cosmati and of medieval Rome, akin to those in the other great basilicas.

The cloister and the portico

Not to be missed:

  • The Romanesque cloister, a peaceful oasis with its medieval colonnade.
  • The entrance portico, with surviving frescoes narrating the stories of St Lawrence and St Stephen.
  • The ancient reused sarcophagi and the inscriptions.

The traces of 1943

The basilica still carries the memory of the bombing of 19 July 1943, which struck the church and the neighborhood hard. The reconstruction, faithful to the original, restored the building; some records recall those days and the historic visit of Pope Pius XII amid the rubble. It is a page of twentieth-century history imprinted on the place.
