Saint Sopatra of Constantinople was the daughter of the emperor Mauricius (582-602). She was inclined towards monasticism, and met St Eustolia in the church of the Most Holy Theotokos at Blachernae. After speaking with the saint, Sopatra finally decided to leave the world and submit her will to her guide, St Eustolia. She transformed the palace building, which her father had given her, into a monastery known for its strict monastic Rule.
St Sopatra died in the year 625.
