The college announced the discovery in Italy by Professor of Art Richard Krautheimer and Professore Enrico Josi of the Commissione di Archaeologia Sacra of the Vatican of a Constantinian chapel dating to the 4th century CE.   The chapel, built into catacombs, lay under the pavement of the church of San Lorenzo fuori le Mura in Rome, and its discovery occurred after Allied bombing during the war destroyed the roof, façade and pavement of the 12th century church.

The excavations were sponsored by the Vatican and, through the Lucy Maynard Salmon Fund for Research, the college.
