The Church of St Mary in Palmis (Italian: Chiesa di Santa Maria delle Piante, Latin: Sanctae Mariae in Palmis), better known as Chiesa del Domine Quo Vadis, is a small church southeast of Rome, central Italy. It is located about some 800 m from Porta San Sebastiano, where the Via Ardeatina branches off the Appian Way, on the site where, according to the legend, Saint Peter met Jesus while the former was fleeing persecution in Rome. According to the apocryphal Acts of Peter, Peter asked Jesus, "Lord, where are you going?" (Latin: Domine, quo vadis?).
