 The church was originally placed by him under the care of the clergy of the Church of S. Crisogono.Due to their neglect of the site, Pope Gregory I ((590–604) handed it over to the members of the newly founded Benedictine Order after the Lombards sacked their monastery of Montecassino in 580.In the seventh century Pope Honorius I (625–638) built a larger church for the increasing numbers of pilgrims; he placed the relics of the saint beneath the high altar, with a window of access from a semi-circular corridor that led behind and below the altar.
