A Palace Chapel Becomes a Pilgrimage Basilica

Santa Croce in Gerusalemme takes its name, "Holy Cross in Jerusalem," from the tradition that Helena, mother of the emperor Constantine, had earth from Jerusalem itself brought to Rome and spread beneath the chapel's floor, so that the building would stand on holy ground rather than merely house holy objects. The church grew out of a hall within Helena's own Roman residence, the Sessorian Palace, converted to Christian use in the fourth century as the empire itself turned Christian, one of a small number of Roman churches with a claimed direct imperial foundation rather than a later ecclesiastical one.

Centuries of rebuilding followed, most visibly an eighteenth century remodelling that gave the basilica its present curved Baroque facade, quite unlike its late antique origins. The relics themselves were reorganised into a dedicated chapel in the 1930s, gathering objects that earlier centuries had kept in various parts of the church into a single space designed for pilgrimage viewing. The basilica today functions as one of Rome's seven traditional pilgrim churches, its relic chapel a stop on a route that predates the modern tourist itinerary by well over a thousand years. The route is walked today by pilgrims and tourists alike, and the basilica remains an active parish church rather than a museum piece by another name.
