The Church of Cassian (Arabic: القسيان), also called the Church of St. Peter (gr. Hagios Petros), was the Cathedral church of Patriarch of Antioch during late antiquity and the Middle Ages. The church is not to be mistaken with the cave church called St. Peter.
A version of the Holy Lance was found in the treasury of the cathedral in 1098, by the forces of the First Crusade. In 1190, the cathedral became the burial place of Frederick Barbarossa. In 1268, the cathedral was burned by Baybars during his sack of Antioch.
