The church survived until the 11th century, when it was abandoned. Thereafter it was liberally plundered for sculptures and other architectural elements (spolia) by both the Byzantines and, after the sack of the city in 1204, by the Crusaders. Several pieces from St. Polyeuctus were reused in the Monastery of Christ Pantokrator (the modern Zeyrek Mosque), and various pieces such as capitals were spread to places as far as Venice, Barcelona and Vienna, including the so-called "Pilastri Acritani" ("Pillars of Acre") in St Mark's Basilica, Venice.
