This is one of the largest and most significant Benedictine abbeys on the eastern coast of the Adriatic. It is mentioned for the first time in the Deed of Donation of Deacon Petar from around the year 1020. The convent was founded and built by the citizens of the city of Split, who, until 1442, had the right to participate in the selection of the abbot, who was, after the bishop and the duke, the most respected citizen of Split. The most well-known monk from the convent was the last Croatian king, Stjepan II. Trpimirović. The architectural complex of the convent consisted of the church, the cloister, and residential buildings. The church furniture included a gable depicting Christ on the throne, a relief of a winged lion holding a man in his front paws, and a sculpture or St. Stephen the Protomartyr from 1355.
