Santa Maria in Palmis (; ), also known as Chiesa del Domine Quo Vadis, is a small church southeast of Rome. 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 apocryphal Acts of Peter, Saint Peter met the risen Christ while Petrus was fleeing persecution in Rome. According to the tradition, Peter asked him, "Lord, where are you going?" (). Christ answered, "I am going to Rome to be crucified again" (). History There has been a sanctuary on the spot since the ninth century, but the current church is from 1637. The current façade was added in the 17th century. It has been supposed that the sanctuary might have been even more ancient, perhaps a Christian adaptation of some already existing temple: the church is in fact located just in front of the sacred campus dedicated to Rediculus, the Roman "God of the Return".

Those travellers who returned also stopped to thank the god for the happy outcome of their journey. The presence of the Apostle Peter in this area, where he is supposed to have lived, appears to be confirmed in an epigraph in the Catacombs of Saint Sebastian that reads Domus Petri (). An epigram by Pope Damasus I (366–384) in honor of Peter and Paul reads: "You that are looking for the names of Peter and Paul, you must know that the saints have lived here." The two footprints on a marble slab at the center of the church — nowadays a copy of the original, which is kept in the nearby Basilica of San Sebastiano fuori le mura — are popularly held to be a miraculous sign left by Jesus. It is to these footprints that the official name of the church alludes: palmis refers to the soles of Jesus' feet. It is likely that these footprints are actually the draft of an ancient Roman "ex voto", a tribute paid to the gods for the good outcome of a journey. There was an inscription above the front door on the church's façade which used to say: "Stop
