The Cathedral of St Anastasia is a monumental Romanesque building, and it carries the name of the Sirmian martyr, to whom two popes bowed down; Alexander the III, who visited her tomb, and Pope John Paul II, who bowed down in 2003 in front of the main gate of the Cathedral.Zadar's Cathedral of St Anastasia was built in the 12th and 13th centuries, upon an older building from the 9th and 11th centuries, and which was erected on the site of an Early Christian Basilica, so the Cathedral’s first stages date as early as the 4th and 5th centuries. The Basilica was dedicated to St Peter the Apostle, but when the Zadar bishop Donat got the relics of the Sirmian martyr St Anastasia, in Zadar known as Stošija, at the beginning of the 9th century, the Basilica was named after her.
