Castritian of Milan

Saint Castritian was bishop of Milan in the middle of the third century, the third bishop of the city. The Catholic Church honours him as a saint, and he is commemorated on 1 December.

Almost nothing is known of his life and episcopate, except that he was bishop of Milan in the mid third century and that his body was buried in a cemetery in the area of Porta Romana, not far from the present Basilica of Saint Calimerius. His relics were later moved to the church of San Giovanni in Conca, demolished between the nineteenth and twentieth centuries. Medieval texts, such as the Historia Dataria of the eleventh century, add details that must be regarded as legendary: the length of his episcopate, forty-⁠one years, its start shortly after Domitian, in 97, and his death in 138. Also legendary is his consecration as a church of a house donated by a certain Philip, though modern scholars, relying on fourth-⁠century documents, consider likely the early existence of a house church with a garden in the area between Porta Ticinese and Porta Magenta.
